### Question: What are the stages of Prostate Cancer ? ### Answer:

Key Points - After prostate cancer has been diagnosed, tests are done to find out if cancer cells have spread within the prostate or to other parts of the body. - There are three ways that cancer spreads in the body. - Cancer may spread from where it began to other parts of the body. - The following stages are used for prostate cancer: - Stage I - Stage II - Stage III - Stage IV After prostate cancer has been diagnosed, tests are done to find out if cancer cells have spread within the prostate or to other parts of the body. The process used to find out if cancer has spread within the prostate or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. The results of the tests used to diagnose prostate cancer are often also used to stage the disease. (See the General Information section.) In prostate cancer, staging tests may not be done unless the patient has symptoms or signs that the cancer has spread, such as bone pain, a high PSA level, or a high Gleason score. The following tests and procedures also may be used in the staging process: - Bone scan : A procedure to check if there are rapidly dividing cells, such as cancer cells, in the bone. A very small amount of radioactive material is injected into a vein and travels through the bloodstream. The radioactive material collects in the bones and is detected by a scanner. - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI). - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - Pelvic lymphadenectomy : A surgical procedure to remove the lymph nodes in the pelvis. A pathologist views the tissue under a microscope to look for cancer cells. - Seminal vesicle biopsy : The removal of fluid from the seminal vesicles (glands that make semen) using a needle. A pathologist views the fluid under a microscope to look for cancer cells. - ProstaScint scan : A procedure to check for cancer that has spread from the prostate to other parts of the body, such as the lymph nodes. A very small amount of radioactive material is injected into a vein and travels through the bloodstream. The radioactive material attaches to prostate cancer cells and is detected by a scanner. The radioactive material shows up as a bright spot on the picture in areas where there are a lot of prostate cancer cells. The stage of the cancer is based on the results of the staging and diagnostic tests, including the prostate-specific antigen (PSA) test and the Gleason score. The tissue samples removed during the biopsy are used to find out the Gleason score. The Gleason score ranges from 2-10 and describes how different the cancer cells look from normal cells and how likely it is that the tumor will spread. The lower the number, the less likely the tumor is to spread. There are three ways that cancer spreads in the body. Cancer can spread through tissue, the lymph system, and the blood: - Tissue. The cancer spreads from where it began by growing into nearby areas. - Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body. - Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body. Cancer may spread from where it began to other parts of the body. When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood. - Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body. - Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body. The metastatic tumor is the same type of cancer as the primary tumor. For example, if prostate cancer spreads to the bone, the cancer cells in the bone are actually prostate cancer cells. The disease is metastatic prostate cancer, not bone cancer. Denosumab, a monoclonal antibody, may be used to prevent bone metastases. The following stages are used for prostate cancer: Stage I In stage I, cancer is found in the prostate only. The cancer: - is found by needle biopsy (done for a high PSA level) or in a small amount of tissue during surgery for other reasons (such as benign prostatic hyperplasia). The PSA level is lower than 10 and the Gleason score is 6 or lower; or - is found in one-half or less of one lobe of the prostate. The PSA level is lower than 10 and the Gleason score is 6 or lower; or - cannot be felt during a digital rectal exam and cannot be seen in imaging tests. Cancer is found in one-half or less of one lobe of the prostate. The PSA level and the Gleason score are not known. Stage II In stage II, cancer is more advanced than in stage I, but has not spread outside the prostate. Stage II is divided into stages IIA and IIB. In stage IIA, cancer: - is found by needle biopsy (done for a high PSA level) or in a small amount of tissue during surgery for other reasons (such as benign prostatic hyperplasia). The PSA level is lower than 20 and the Gleason score is 7; or - is found by needle biopsy (done for a high PSA level) or in a small amount of tissue during surgery for other reasons (such as benign prostatic hyperplasia). The PSA level is at least 10 but lower than 20 and the Gleason score is 6 or lower; or - is found in one-half or less of one lobe of the prostate. The PSA level is at least 10 but lower than 20 and the Gleason score is 6 or lower; or - is found in one-half or less of one lobe of the prostate. The PSA level is lower than 20 and the Gleason score is 7; or - is found in more than one-half of one lobe of the prostate. In stage IIB, cancer: - is found in opposite sides of the prostate. The PSA can be any level and the Gleason score can range from 2 to 10; or - cannot be felt during a digital rectal exam and cannot be seen in imaging tests. The PSA level is 20 or higher and the Gleason score can range from 2 to 10; or - cannot be felt during a digital rectal exam and cannot be seen in imaging tests. The PSA can be any level and the Gleason score is 8 or higher. Stage III In stage III, cancer has spread beyond the outer layer of the prostate and may have spread to the seminal vesicles. The PSA can be any level and the Gleason score can range from 2 to 10. Stage IV In stage IV, the PSA can be any level and the Gleason score can range from 2 to 10. Also, cancer: - has spread beyond the seminal vesicles to nearby tissue or organs, such as the rectum, bladder, or pelvic wall; or - may have spread to the seminal vesicles or to nearby tissue or organs, such as the rectum, bladder, or pelvic wall. Cancer has spread to nearby lymph nodes; or - has spread to distant parts of the body, which may include lymph nodes or bones. Prostate cancer often spreads to the bones.

### Question: What are the treatments for Merkel Cell Carcinoma ? ### Answer:

Key Points - There are different types of treatment for patients with Merkel cell carcinoma. - Three types of standard treatment are used: - Surgery - Radiation therapy - Chemotherapy - New types of treatment are being tested in clinical trials. - Treatment for Merkel cell carcinoma may cause side effects. - Patients may want to think about taking part in a clinical trial. - Patients can enter clinical trials before, during, or after starting their cancer treatment. - Follow-up tests may be needed. There are different types of treatment for patients with Merkel cell carcinoma. Different types of treatments are available for patients with Merkel cell carcinoma. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment. Three types of standard treatment are used: Surgery One or more of the following surgical procedures may be used to treat Merkel cell carcinoma: - Wide local excision: The cancer is cut from the skin along with some of the tissue around it. A sentinel lymph node biopsy may be done during the wide local excision procedure. If there is cancer in the lymph nodes, a lymph node dissection also may be done. - Lymph node dissection: A surgical procedure in which the lymph nodes are removed and a sample of tissue is checked under a microscope for signs of cancer. For a regional lymph node dissection, some of the lymph nodes in the tumor area are removed; for a radical lymph node dissection, most or all of the lymph nodes in the tumor area are removed. This procedure is also called lymphadenectomy. Even if the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given chemotherapy or radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy. Radiation therapy Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy: - External radiation therapy uses a machine outside the body to send radiation toward the cancer. - Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type and stage of the cancer being treated. External radiation therapy is used to treat Merkel cell carcinoma, and may also be used as palliative therapy to relieve symptoms and improve quality of life. Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated. New types of treatment are being tested in clinical trials. Treatment for Merkel cell carcinoma may cause side effects. For information about side effects caused by treatment for cancer, see our Side Effects page. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Patients can enter clinical trials before, during, or after starting their cancer treatment. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials. Follow-up tests may be needed. Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups. Treatment Options by Stage Stage I and Stage II Merkel Cell Carcinoma Treatment of stage I and stage II Merkel cell carcinoma may include the following: - Surgery to remove the tumor, such as wide local excision with or without lymph node dissection. - Radiation therapy after surgery. - A clinical trial of a new treatment. Check the list of NCI-supported cancer clinical trials that are now accepting patients with stage I neuroendocrine carcinoma of the skin and stage II neuroendocrine carcinoma of the skin. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website. Stage III Merkel Cell Carcinoma Treatment of stage III Merkel cell carcinoma may include the following: - Wide local excision with or without lymph node dissection. - Radiation therapy. - A clinical trial of chemotherapy. Check the list of NCI-supported cancer clinical trials that are now accepting patients with stage III neuroendocrine carcinoma of the skin. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website. Stage IV Merkel Cell Carcinoma Treatment of stage IV Merkel cell carcinoma may include the following as palliative treatment to relieve symptoms and improve quality of life: - Chemotherapy. - Surgery. - Radiation therapy. - A clinical trial of a new treatment. Check the list of NCI-supported cancer clinical trials that are now accepting patients with stage IV neuroendocrine carcinoma of the skin. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website.

### Question: How to prevent Colorectal Cancer ? ### Answer:

Key Points - Avoiding risk factors and increasing protective factors may help prevent cancer. - The following risk factors increase the risk of colorectal cancer: - Age - Family history of colorectal cancer - Personal history - Inherited risk - Alcohol - Cigarette smoking - Obesity - The following protective factors decrease the risk of colorectal cancer: - Physical activity - Aspirin - Combination hormone replacement therapy - Polyp removal - It is not clear if the following affect the risk of colorectal cancer: - Nonsteroidal anti-inflammatory drugs (NSAIDs) other than aspirin - Calcium - Diet - The following factors do not affect the risk of colorectal cancer: - Hormone replacement therapy with estrogen only - Statins - Cancer prevention clinical trials are used to study ways to prevent cancer. - New ways to prevent colorectal cancer are being studied in clinical trials. Avoiding risk factors and increasing protective factors may help prevent cancer. Avoiding cancer risk factors may help prevent certain cancers. Risk factors include smoking, being overweight, and not getting enough exercise. Increasing protective factors such as quitting smoking and exercising may also help prevent some cancers. Talk to your doctor or other health care professional about how you might lower your risk of cancer. The following risk factors increase the risk of colorectal cancer: Age The risk of colorectal cancer increases after age 50. Most cases of colorectal cancer are diagnosed after age 50. Family history of colorectal cancer Having a parent, brother, sister, or child with colorectal cancer doubles a person's risk of colorectal cancer. Personal history Having a personal history of the following conditions increases the risk of colorectal cancer: - Previous colorectal cancer. - High-risk adenomas (colorectal polyps that are 1 centimeter or larger in size or that have cells that look abnormal under a microscope). - Ovarian cancer. - Inflammatory bowel disease (such as ulcerative colitis or Crohn disease). Inherited risk The risk of colorectal cancer is increased when certain gene changes linked to familial adenomatous polyposis (FAP) or hereditary nonpolyposis colon cancer (HNPCC or Lynch Syndrome) are inherited. Alcohol Drinking 3 or more alcoholic beverages per day increases the risk of colorectal cancer. Drinking alcohol is also linked to the risk of forming large colorectal adenomas (benign tumors). Cigarette smoking Cigarette smoking is linked to an increased risk of colorectal cancer and death from colorectal cancer. Smoking cigarettes is also linked to an increased risk of forming colorectal adenomas. Cigarette smokers who have had surgery to remove colorectal adenomas are at an increased risk for the adenomas to recur (come back). Obesity Obesity is linked to an increased risk of colorectal cancer and death from colorectal cancer. The following protective factors decrease the risk of colorectal cancer: Physical activity A lifestyle that includes regular physical activity is linked to a decreased risk of colorectal cancer. Aspirin Studies have shown that taking aspirin lowers the risk of colorectal cancer and the risk of death from colorectal cancer. The decrease in risk begins 10 to 20 years after patients start taking aspirin. The possible harms of aspirin use (100 mg or less) daily or every other day include an increased risk of stroke and bleeding in the stomach and intestines. These risks may be greater among the elderly, men, and those with conditions linked to a higher than normal risk of bleeding. Combination hormone replacement therapy Studies have shown that combination hormone replacement therapy (HRT) that includes both estrogen and progestin lowers the risk of invasive colorectal cancer in postmenopausal women. However, in women who take combination HRT and do develop colorectal cancer, the cancer is more likely to be advanced when it is diagnosed and the risk of dying from colorectal cancer is not decreased. The possible harms of combination HRT include an increased risk of having: - Breast cancer. - Heart disease. - Blood clots. Polyp removal Most colorectal polyps are adenomas, which may develop into cancer. Removing colorectal polyps that are larger than 1 centimeter (pea-sized) may lower the risk of colorectal cancer. It is not known if removing smaller polyps lowers the risk of colorectal cancer. The possible harms of polyp removal during colonoscopy or sigmoidoscopy include a tear in the wall of the colon and bleeding. It is not clear if the following affect the risk of colorectal cancer: Nonsteroidal anti-inflammatory drugs (NSAIDs) other than aspirin It is not known if the use of nonsteroidal anti-inflammatory drugs or NSAIDs (such as sulindac, celecoxib, naproxen, and ibuprofen) lowers the risk of colorectal cancer. Studies have shown that taking the nonsteroidal anti-inflammatory drug celecoxib reduces the risk of colorectal adenomas (benign tumors) coming back after they have been removed. It is not clear if this results in a lower risk of colorectal cancer. Taking sulindac or celecoxib has been shown to reduce the number and size of polyps that form in the colon and rectum of people with familial adenomatous polyposis (FAP). It is not clear if this results in a lower risk of colorectal cancer. The possible harms of NSAIDs include: - Kidney problems. - Bleeding in the stomach, intestines, or brain. - Heart problems such as heart attack and congestive heart failure. Calcium It is not known if taking calcium supplements lowers the risk of colorectal cancer. Diet It is not known if a diet low in fat and meat and high in fiber, fruits, and vegetables lowers the risk of colorectal cancer. Some studies have shown that a diet high in fat, proteins, calories, and meat increases the risk of colorectal cancer, but other studies have not. The following factors do not affect the risk of colorectal cancer: Hormone replacement therapy with estrogen only Hormone replacement therapy with estrogen only does not lower the risk of having invasive colorectal cancer or the risk of dying from colorectal cancer. Statins Studies have shown that taking statins (drugs that lower cholesterol) does not increase or decrease the risk of colorectal cancer. Cancer prevention clinical trials are used to study ways to prevent cancer. Cancer prevention clinical trials are used to study ways to lower the risk of developing certain types of cancer. Some cancer prevention trials are conducted with healthy people who have not had cancer but who have an increased risk for cancer. Other prevention trials are conducted with people who have had cancer and are trying to prevent another cancer of the same type or to lower their chance of developing a new type of cancer. Other trials are done with healthy volunteers who are not known to have any risk factors for cancer. The purpose of some cancer prevention clinical trials is to find out whether actions people take can prevent cancer. These may include exercising more or quitting smoking or taking certain medicines, vitamins, minerals, or food supplements. New ways to prevent colorectal cancer are being studied in clinical trials. Clinical trials are taking place in many parts of the country. Information about clinical trials can be found in the Clinical Trials section of the NCI website. Check NCI's list of cancer clinical trials for colon cancer prevention trials or rectal cancer prevention trials that are now accepting patients.

### Question: What are the treatments for Male Breast Cancer ? ### Answer:

Key Points - There are different types of treatment for men with breast cancer. - Five types of standard treatment are used to treat men with breast cancer: - Surgery - Chemotherapy - Hormone therapy - Radiation therapy - Targeted therapy - Treatment for male breast cancer may cause side effects. There are different types of treatment for men with breast cancer. Different types of treatment are available for men with breast cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. For some patients, taking part in a clinical trial may be the best treatment choice. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. Information about clinical trials is available from the NCI website. Choosing the most appropriate cancer treatment is a decision that ideally involves the patient, family, and health care team. Five types of standard treatment are used to treat men with breast cancer: Surgery Surgery for men with breast cancer is usually a modified radical mastectomy (removal of the breast, many of the lymph nodes under the arm, the lining over the chest muscles, and sometimes part of the chest wall muscles). Breast-conserving surgery, an operation to remove the cancer but not the breast itself, is also used for some men with breast cancer. A lumpectomy is done to remove the tumor (lump) and a small amount of normal tissue around it. Radiation therapy is given after surgery to kill any cancer cells that are left. Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated. See Drugs Approved for Breast Cancer for more information. Hormone therapy Hormone therapy is a cancer treatment that removes hormones or blocks their action and stops cancer cells from growing. Hormones are substances made by glands in the body and circulated in the bloodstream. Some hormones can cause certain cancers to grow. If tests show that the cancer cells have places where hormones can attach (receptors), drugs, surgery, or radiation therapy is used to reduce the production of hormones or block them from working. See Drugs Approved for Breast Cancer for more information. Radiation therapy Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy: - External radiation therapy uses a machine outside the body to send radiation toward the cancer. - Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type and stage of the cancer being treated. External radiation therapy is used to treat male breast cancer. Targeted therapy Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Monoclonal antibody therapy is a type of targeted therapy used to treat men with breast cancer. Monoclonal antibody therapy uses antibodies made in the laboratory from a single type of immune system cell. These antibodies can identify substances on cancer cells or normal substances that may help cancer cells grow. The antibodies attach to the substances and kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells. Monoclonal antibodies are also used with chemotherapy as adjuvant therapy (treatment given after surgery to lower the risk that the cancer will come back). Trastuzumab is a monoclonal antibody that blocks the effects of the growth factor protein HER2. See Drugs Approved for Breast Cancer for more information. Treatment for male breast cancer may cause side effects. For information about side effects caused by treatment for cancer, see our Side Effects page. Treatment Options for Male Breast Cancer Initial Surgery Treatment for men diagnosed with breast cancer is usually modified radical mastectomy. Breast-conserving surgery with lumpectomy may be used for some men. Adjuvant Therapy Therapy given after an operation when cancer cells can no longer be seen is called adjuvant therapy. Even if the doctor removes all the cancer that can be seen at the time of the operation, the patient may be given radiation therapy, chemotherapy, hormone therapy, and/or targeted therapy after surgery, to try to kill any cancer cells that may be left. - Node-negative: For men whose cancer is node-negative (cancer has not spread to the lymph nodes), adjuvant therapy should be considered on the same basis as for a woman with breast cancer because there is no evidence that response to therapy is different for men and women. - Node-positive: For men whose cancer is node-positive (cancer has spread to the lymph nodes), adjuvant therapy may include the following: - Chemotherapy plus tamoxifen (to block the effect of estrogen). - Other hormone therapy. - Targeted therapy with a monoclonal antibody (trastuzumab). These treatments appear to increase survival in men as they do in women. The patients response to hormone therapy depends on whether there are hormone receptors (proteins) in the tumor. Most breast cancers in men have these receptors. Hormone therapy is usually recommended for male breast cancer patients, but it can have many side effects, including hot flashes and impotence (the inability to have an erection adequate for sexual intercourse). Distant Metastases Treatment for men with distant metastases (cancer that has spread to other parts of the body) may be hormone therapy, chemotherapy, or both. Hormone therapy may include the following: - Orchiectomy (the removal of the testicles to decrease the amount of hormone made). - Luteinizing hormone-releasing hormone agonist with or without total androgen blockade (to decrease the the amount of sex hormones made). - Tamoxifen for cancer that is estrogen-receptor positive. - Progestin (a female hormone made in a laboratory). - Aromatase inhibitors (to decrease the amount of estrogen made). Hormone therapies may be used in sequence (one after the other). Standard chemotherapy regimens may be used if hormone therapy does not work. Men usually respond to therapy in the same way as women who have breast cancer.

### Question: How to diagnose Zollinger-Ellison Syndrome ? ### Answer:

A health care provider diagnoses Zollinger-Ellison syndrome based on the following: - medical history - physical exam - signs and symptoms - blood tests - upper gastrointestinal (GI) endoscopy - imaging tests to look for gastrinomas - measurement of stomach acid Medical History Taking a medical and family history is one of the first things a health care provider may do to help diagnose Zollinger-Ellison syndrome. The health care provider may ask about family cases of MEN1 in particular. Physical Exam A physical exam may help diagnose Zollinger-Ellison syndrome. During a physical exam, a health care provider usually - examines a persons body - uses a stethoscope to listen to bodily sounds - taps on specific areas of the persons body Signs and Symptoms A health care provider may suspect Zollinger-Ellison syndrome if - diarrhea accompanies peptic ulcer symptoms or if peptic ulcer treatment fails. - a person has peptic ulcers without the use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen or a bacterial Helicobacter pylori (H. pylori) infection. NSAID use and H. pylori infection may cause peptic ulcers. - a person has severe ulcers that bleed or cause holes in the duodenum or stomach. - a health care provider diagnoses a person or the persons family member with MEN1 or a person has symptoms of MEN1. Blood Tests The health care provider may use blood tests to check for an elevated gastrin level. A technician or nurse draws a blood sample during an office visit or at a commercial facility and sends the sample to a lab for analysis. A health care provider will ask the person to fast for several hours prior to the test and may ask the person to stop acid-reducing medications for a period of time before the test. A gastrin level that is 10 times higher than normal suggests Zollinger-Ellison syndrome.2 A health care provider may also check for an elevated gastrin level after an infusion of secretin. Secretin is a hormone that causes gastrinomas to release more gastrin. A technician or nurse places an intravenous (IV) needle in a vein in the arm to give an infusion of secretin. A health care provider may suspect Zollinger-Ellison syndrome if blood drawn after the infusion shows an elevated gastrin level. Upper Gastrointestinal Endoscopy The health care provider uses an upper GI endoscopy to check the esophagus, stomach, and duodenum for ulcers and esophagitisa general term used to describe irritation and swelling of the esophagus. This procedure involves using an endoscopea small, flexible tube with a lightto see the upper GI tract, which includes the esophagus, stomach, and duodenum. A gastroenterologista doctor who specializes in digestive diseasesperforms the test at a hospital or an outpatient center. The gastroenterologist carefully feeds the endoscope down the esophagus and into the stomach and duodenum. A small camera mounted on the endoscope transmits a video image to a monitor, allowing close examination of the intestinal lining. A person may receive a liquid anesthetic that is gargled or sprayed on the back of the throat. A technician or nurse inserts an IV needle in a vein in the arm if anesthesia is given. Imaging Tests To help find gastrinomas, a health care provider may order one or more of the following imaging tests: - Computerized tomography (CT) scan. A CT scan is an x ray that produces pictures of the body. A CT scan may include the injection of a special dye, called contrast medium. CT scans use a combination of x rays and computer technology to create images. CT scans require the person to lie on a table that slides into a tunnel-shaped device where an x-ray technician takes x rays. A computer puts the different views together to create a model of the pancreas, stomach, and duodenum. The x-ray technician performs the procedure in an outpatient center or a hospital, and a radiologista doctor who specializes in medical imaginginterprets the images. The person does not need anesthesia. CT scans can show tumors and ulcers. - Magnetic resonance imaging (MRI). MRI is a test that takes pictures of the bodys internal organs and soft tissues without using x rays. A specially trained technician performs the procedure in an outpatient center or a hospital, and a radiologist interprets the images. The person does not need anesthesia, though people with a fear of confined spaces may receive light sedation, taken by mouth. An MRI may include the injection of contrast medium. With most MRI machines, the person will lie on a table that slides into a tunnel-shaped device that may be open ended or closed at one end. Some machines allow the person to lie in a more open space. During an MRI, the person, although usually awake, remains perfectly still while the technician takes the images, which usually takes only a few minutes. The technician will take a sequence of images from different angles to create a detailed picture of the upper GI tract. During sequencing, the person will hear loud mechanical knocking and humming noises. - Endoscopic ultrasound. This procedure involves using a special endoscope called an endoechoscope to perform ultrasound of the pancreas. The endoechoscope has a built-in miniature ultrasound probe that bounces safe, painless sound waves off organs to create an image of their structure. A gastroenterologist performs the procedure in an outpatient center or a hospital, and a radiologist interprets the images. The gastroenterologist carefully feeds the endoechoscope down the esophagus, through the stomach and duodenum, until it is near the pancreas. A person may receive a liquid anesthetic that is gargled or sprayed on the back of the throat. A sedative helps the person stay relaxed and comfortable. The images can show gastrinomas in the pancreas. - Angiogram. An angiogram is a special kind of x ray in which an interventional radiologista specially trained radiologistthreads a thin, flexible tube called a catheter through the large arteries, often from the groin, to the artery of interest. The radiologist injects contrast medium through the catheter so the images show up more clearly on the x ray. The interventional radiologist performs the procedure and interprets the images in a hospital or an outpatient center. A person does not need anesthesia, though a light sedative may help reduce a persons anxiety during the procedure. This test can show gastrinomas in the pancreas. - Somatostatin receptor scintigraphy. An x-ray technician performs this test, also called OctreoScan, at a hospital or an outpatient center, and a radiologist interprets the images. A person does not need anesthesia. A radioactive compound called a radiotracer, when injected into the bloodstream, selectively labels tumor cells. The labeled cells light up when scanned with a device called a gamma camera. The test can show gastrinomas in the duodenum, pancreas, and other parts of the body. Small gastrinomas may be hard to see; therefore, health care providers may order several types of imaging tests to find gastrinomas. Stomach-acid Measurement Using a sample of stomach juices for analysis, a health care provider may measure the amount of stomach acid a person produces. During the exam, a health care provider puts in a nasogastric tubea tiny tube inserted through the nose and throat that reaches into the stomach. A person may receive a liquid anesthetic that is gargled or sprayed on the back of the throat. Once the tube is placed, a health care provider takes samples of the stomach acid.

Key Points - There are different types of treatment for patients with small cell lung cancer. - Five types of standard treatment are used: - Surgery - Chemotherapy - Radiation therapy - Laser therapy - Endoscopic stent placement - New types of treatment are being tested in clinical trials. - Patients may want to think about taking part in a clinical trial. - Patients can enter clinical trials before, during, or after starting their cancer treatment. - Follow-up tests may be needed. There are different types of treatment for patients with small cell lung cancer. Different types of treatment are available for patients with small cell lung cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment. Five types of standard treatment are used: Surgery Surgery may be used if the cancer is found in one lung and in nearby lymph nodes only. Because this type of lung cancer is usually found in both lungs, surgery alone is not often used. During surgery, the doctor will also remove lymph nodes to find out if they have cancer in them. Sometimes, surgery may be used to remove a sample of lung tissue to find out the exact type of lung cancer. Even if the doctor removes all the cancer that can be seen at the time of the operation, some patients may be given chemotherapy or radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy. Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated. See Drugs Approved for Small Cell Lung Cancer for more information. Radiation therapy Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy: - External radiation therapy uses a machine outside the body to send radiation toward the cancer. - Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type and stage of the cancer being treated. External radiation therapy is used to treat small cell lung cancer, and may also be used as palliative therapy to relieve symptoms and improve quality of life. Radiation therapy to the brain to lessen the risk that cancer will spread to the brain may also be given. Laser therapy Laser therapy is a cancer treatment that uses a laser beam (a narrow beam of intense light) to kill cancer cells. Endoscopic stent placement An endoscope is a thin, tube-like instrument used to look at tissues inside the body. An endoscope has a light and a lens for viewing and may be used to place a stent in a body structure to keep the structure open. An endoscopic stent can be used to open an airway blocked by abnormal tissue. New types of treatment are being tested in clinical trials. Information about clinical trials is available from the NCI website. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Patients can enter clinical trials before, during, or after starting their cancer treatment. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials. Follow-up tests may be needed. Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups. Treatment Options by Stage Limited-Stage Small Cell Lung Cancer Treatment of limited-stage small cell lung cancer may include the following: - Combination chemotherapy and radiation therapy to the chest. Radiation therapy to the brain may later be given to patients with complete responses. - Combination chemotherapy alone for patients who cannot be given radiation therapy. - Surgery followed by chemotherapy. - Surgery followed by chemotherapy and radiation therapy. - Radiation therapy to the brain may be given to patients who have had a complete response, to prevent the spread of cancer to the brain. - Clinical trials of new chemotherapy, surgery, and radiation treatments. Check the list of NCI-supported cancer clinical trials that are now accepting patients with limited stage small cell lung cancer. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website. Extensive-Stage Small Cell Lung Cancer Treatment of extensive-stage small cell lung cancer may include the following: - Combination chemotherapy. - Radiation therapy to the brain, spine, bone, or other parts of the body where the cancer has spread, as palliative therapy to relieve symptoms and improve quality of life. - Radiation therapy to the chest may be given to patients who respond to chemotherapy. - Radiation therapy to the brain may be given to patients who have had a complete response, to prevent the spread of cancer to the brain. - Clinical trials of new chemotherapy treatments. Check the list of NCI-supported cancer clinical trials that are now accepting patients with extensive stage small cell lung cancer. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug.

### Question: What are the symptoms of Focal dermal hypoplasia ? ### Answer:

What are the signs and symptoms of Focal dermal hypoplasia? Focal dermal hypoplasia is usually evident from birth and primarily affects the skin, skeleton, eyes, and face. The signs and symptoms of vary widely, although almost all affected individuals have skin abnormalities. Some of the skin findings include streaks of very thin skin (dermal hypoplasia), yellowish-pink nodules of fat under the skin, areas where the top layers of skin are absent (cutis aplasia), telangiectases, and streaks of slightly darker or lighter skin. These skin features can cause pain, itching, irritation, or lead to skin infections. With age, most develop wart-like growths, called papillomas, around the nostrils, lips, anus, and female genitalia. They may also be present in the throat, specifically in the esophagus or larynx, and can cause problems with swallowing, breathing, or sleeping. Other features include small, ridged fingernails and toenails as well as sparse, brittle or absent scalp hair. The skeleton is usually affected as well. Many individuals have hand and foot abnormalities, including missing fingers or toes (oligodactyly), webbed or fused fingers or toes (syndactyly), and a deep split in the hands or feet with missing fingers or toes and fusion of the remaining digits (ectrodactyly). X-rays can show streaks of altered bone density, called osteopathia striata, which usually do not cause symptoms. Eye abnormalities are common and can include microphthalmia and anopthalmia as well as problems with the tear ducts. The retina or the optic nerve can also be incompletely developed, which can result in a gap or split in these structures (coloboma). Some of these eye abnormalities do not impair vision, while others can lead to low vision or blindness. People with focal dermal hypoplasia often have distinctive, but subtle facial features such as a pointed chin, small ears, notched nostrils, and a slight difference in the size and shape of the right and left sides of the face (facial asymmetry). Some individuals may have a cleft lip and/or palate. About half of those with focal dermal hypoplasia have teeth abnormalities of their teeth, especially of the enamel (the hard, white material that forms the protective outer layer of each tooth). Less commonly, kidney and gastrointestinal abnormalities are present. The kidneys may be fused together, which can lead to kidney infections. The main gastrointestinal abnormality that is seen is an omphalocele. The Human Phenotype Ontology provides the following list of signs and symptoms for Focal dermal hypoplasia. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms.

Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.

### Question: What are the treatments for Graves' Disease ? ### Answer:

People with Graves disease have three treatment options: radioiodine therapy, medications, and thyroid surgery. Radioiodine therapy is the most common treatment for Graves disease in the United States. Graves disease is often diagnosed and treated by an endocrinologista doctor who specializes in the bodys hormone- secreting glands. Radioiodine Therapy In radioiodine therapy, patients take radioactive iodine-131 by mouth. Because the thyroid gland collects iodine to make thyroid hormone, it will collect the radioactive iodine from the bloodstream in the same way. Iodine-131stronger than the radioactive iodine used in diagnostic testsgradually destroys the cells that make up the thyroid gland but does not affect other body tissues. Many health care providers use a large enough dose of iodine-131 to shut down the thyroid completely, but some prefer smaller doses to try to bring hormone production into the normal range. More than one round of radioiodine therapy may be needed. Results take time and people undergoing this treatment may not notice improvement in symptoms for several weeks or months. People with GO should talk with a health care provider about any risks associated with radioactive iodine treatments. Several studies suggest radioiodine therapy can worsen GO in some people. Other treatments, such as prescription steroids, may prevent this complication. Although iodine-131 is not known to cause birth defects or infertility, radioiodine therapy is not used in pregnant women or women who are breastfeeding. Radioactive iodine can be harmful to the fetus thyroid and can be passed from mother to child in breast milk. Experts recommend that women wait a year after treatment before becoming pregnant. Almost everyone who receives radioactive iodine treatment eventually develops hypothyroidism, which occurs when the thyroid does not make enough thyroid hormone. People with hypothyroidism must take synthetic thyroid hormone, a medication that replaces their natural thyroid hormone. Medications Beta blockers. Health care providers may prescribe a medication called a beta blocker to reduce many of the symptoms of hyperthyroidism, such as tremors, rapid heartbeat, and nervousness. But beta blockers do not stop thyroid hormone production. Anti-thyroid medications. Health care providers sometimes prescribe anti-thyroid medications as the only treatment for Graves disease. Anti-thyroid medications interfere with thyroid hormone production but dont usually have permanent results. Use of these medications requires frequent monitoring by a health care provider. More often, anti-thyroid medications are used to pretreat patients before surgery or radioiodine therapy, or they are used as supplemental treatment after radioiodine therapy. Anti-thyroid medications can cause side effects in some people, including - allergic reactions such as rashes and itching - a decrease in the number of white blood cells in the body, which can lower a persons resistance to infection - liver failure, in rare cases In the United States, health care providers prescribe the anti-thyroid medication methimazole (Tapazole, Northyx) for most types of hyperthyroidism. Anti-thyroid medications and pregnancy. Because pregnant and breastfeeding women cannot receive radioiodine therapy, they are usually treated with an anti-thyroid medication instead. However, experts agree that women in their first trimester of pregnancy should probably not take methimazole due to the rare occurrence of damage to the fetus. Another anti-thyroid medication, propylthiouracil (PTU), is available for women in this stage of pregnancy or for women who are allergic to or intolerant of methimazole and have no other treatment options. Health care providers may prescribe PTU for the first trimester of pregnancy and switch to methimazole for the second and third trimesters. Some women are able to stop taking anti-thyroid medications in the last 4 to 8 weeks of pregnancy due to the remission of hyperthyroidism that occurs during pregnancy. However, these women should continue to be monitored for recurrence of thyroid problems following delivery. Studies have shown that mothers taking anti-thyroid medications may safely breastfeed. However, they should take only moderate doses, less than 1020 milligrams daily, of the anti-thyroid medication methimazole. Doses should be divided and taken after feedings, and the infants should be monitored for side effects.2 Women requiring higher doses of the anti-thyroid medication to control hyperthyroidism should not breastfeed. 2Ogunyemi DA. Autoimmune thyroid disease and pregnancy. emedicine website. emedicine.medscape.com/article/261913-overview. Updated March 12, 2012. Accessed April 10, 2012. Stop your anti-thyroid medication and call your health care provider right away if you develop any of the following while taking anti-thyroid medications: - fatigue - weakness - vague abdominal pain - loss of appetite - skin rash or itching - easy bruising - yellowing of the skin or whites of the eyes, called jaundice - persistent sore throat - fever Thyroid Surgery Surgery is the least-used option for treating Graves disease. Sometimes surgery may be used to treat - pregnant women who cannot tolerate anti-thyroid medications - people suspected of having thyroid cancer, though Graves disease does not cause cancer - people for whom other forms of treatment are not successful Before surgery, the health care provider may prescribe anti-thyroid medications to temporarily bring a patients thyroid hormone levels into the normal range. This presurgical treatment prevents a condition called thyroid storma sudden, severe worsening of symptomsthat can occur when hyperthyroid patients have general anesthesia. When surgery is used, many health care providers recommend the entire thyroid be removed to eliminate the chance that hyperthyroidism will return. If the entire thyroid is removed, lifelong thyroid hormone medication is necessary. Although uncommon, certain problems can occur in thyroid surgery. The parathyroid glands can be damaged because they are located very close to the thyroid. These glands help control calcium and phosphorous levels in the body. Damage to the laryngeal nerve, also located close to the thyroid, can lead to voice changes or breathing problems. But when surgery is performed by an experienced surgeon, less than 1 percent of patients have permanent complications.1 People who need help finding a surgeon can contact one of the organizations listed under For More Information. Eye Care The eye problems associated with Graves disease may not improve following thyroid treatment, so the two problems are often treated separately. Eye drops can relieve dry, gritty, irritated eyesthe most common of the milder symptoms. If pain and swelling occur, health care providers may prescribe a steroid such as prednisone. Other medications that suppress the immune response may also provide relief. Special lenses for glasses can help with light sensitivity and double vision. People with eye symptoms may be advised to sleep with their head elevated to reduce eyelid swelling. If the eyelids do not fully close, taping them shut at night can help prevent dry eyes. In more severe cases, external radiation may be applied to the eyes to reduce inflammation. Like other types of radiation treatment, the benefits are not immediate; most people feel relief from symptoms 1 to 2 months after treatment. Surgery may be used to improve bulging of the eyes and correct the vision changes caused by pressure on the optic nerve. A procedure called orbital decompression makes the eye socket bigger and gives the eye room to sink back to a more normal position. Eyelid surgery can return retracted eyelids to their normal position.

### Question: How to diagnose Arrhythmia ? ### Answer:

Arrhythmias can be hard to diagnose, especially the types that only cause symptoms every once in a while. Doctors diagnose arrhythmias based on medical and family histories, a physical exam, and the results from tests and procedures. Specialists Involved Doctors who specialize in the diagnosis and treatment of heart diseases include: Cardiologists. These doctors diagnose and treat adults who have heart problems. Pediatric cardiologists. These doctors diagnose and treat babies, children, and youth who have heart problems. Electrophysiologists. These doctors are cardiologists or pediatric cardiologists who specialize in arrhythmias. Medical and Family Histories To diagnose an arrhythmia, your doctor may ask you to describe your symptoms. He or she may ask whether you feel fluttering in your chest and whether you feel dizzy or light-headed. Your doctor also may ask whether you have other health problems, such as a history of heart disease, high blood pressure, diabetes, or thyroid problems. He or she may ask about your family's medical history, including whether anyone in your family: Has a history of arrhythmias Has ever had heart disease or high blood pressure Has died suddenly Has other illnesses or health problems Your doctor will likely want to know what medicines you're taking, including over-the-counter medicines and supplements. Your doctor may ask about your health habits, such as physical activity, smoking, or using alcohol or drugs (for example, cocaine). He or she also may want to know whether you've had emotional stress or anger. Physical Exam During a physical exam, your doctor may: Listen to the rate and rhythm of your heartbeat Listen to your heart for a heart murmur (an extra or unusual sound heard during your heartbeat) Check your pulse to find out how fast your heart is beating Check for swelling in your legs or feet, which could be a sign of an enlarged heart or heart failure Look for signs of other diseases, such as thyroid disease, that could be causing the problem Diagnostic Tests and Procedures EKG (Electrocardiogram) An EKG is a simple, painless test that detects and records the heart's electrical activity. It's the most common test used to diagnose arrhythmias. An EKG shows how fast the heart is beating and its rhythm (steady or irregular). It also records the strength and timing of electrical signals as they pass through the heart. A standard EKG only records the heartbeat for a few seconds. It won't detect arrhythmias that don't happen during the test. To diagnose arrhythmias that come and go, your doctor may have you wear a portable EKG monitor. The two most common types of portable EKGs are Holter and event monitors. Holter and Event Monitors A Holter monitor records the heart's electrical signals for a full 24- or 48-hour period. You wear one while you do your normal daily activities. This allows the monitor to record your heart for a longer time than a standard EKG. An event monitor is similar to a Holter monitor. You wear an event monitor while doing your normal activities. However, an event monitor only records your heart's electrical activity at certain times while you're wearing it. For many event monitors, you push a button to start the monitor when you feel symptoms. Other event monitors start automatically when they sense abnormal heart rhythms. Some event monitors are able to send data about your heart's electrical activity to a central monitoring station. Technicians at the station review the information and send it to your doctor. You also can use the device to report any symptoms you're having. You can wear an event monitor for weeks or until symptoms occur. Other Tests Other tests also are used to help diagnose arrhythmias. Blood tests. Blood tests check the level of substances in the blood, such as potassium and thyroid hormone. Abnormal levels of these substances can increase your chances of having an arrhythmia. Chest x ray. A chest x ray is a painless test that creates pictures of the structures in your chest, such as your heart and lungs. This test can show whether your heart is enlarged. Echocardiography. This test uses sound waves to create a moving picture of your heart. Echocardiography (echo) provides information about the size and shape of your heart and how well your heart chambers and valves are working. The test also can identify areas of poor blood flow to the heart, areas of heart muscle that aren't contracting normally, and previous injury to the heart muscle caused by poor blood flow. There are several types of echo, including stress echo. This test is done both before and after a stress test (see below). A stress echo usually is done to find out whether you have decreased blood flow to your heart, a sign of coronary heart disease (CHD). A transesophageal (tranz-ih-sof-uh-JEE-ul) echo, or TEE, is a special type of echo that takes pictures of the heart through the esophagus. The esophagus is the passage leading from your mouth to your stomach. Stress test. Some heart problems are easier to diagnose when your heart is working hard and beating fast. During stress testing, you exercise to make your heart work hard and beat fast while heart tests are done. If you can't exercise, you may be given medicine to make your heart work hard and beat fast. The heart tests done during stress testing may include nuclear heart scanning, echo, and positron emission tomography (PET) scanning of the heart. Electrophysiology study (EPS). This test is used to assess serious arrhythmias. During an EPS, a thin, flexible wire is passed through a vein in your groin (upper thigh) or arm to your heart. The wire records your heart's electrical signals. Your doctor can use the wire to electrically stimulate your heart and trigger an arrhythmia. This allows your doctor to see whether an antiarrhythmia medicine can stop the problem. Catheter ablation, a procedure used to treat some arrhythmias, may be done during an EPS. Tilt table testing. This test sometimes is used to help find the cause of fainting spells. You lie on a table that moves from a lying down to an upright position. The change in position may cause you to faint. Your doctor watches your symptoms, heart rate, EKG reading, and blood pressure throughout the test. He or she may give you medicine and then check your response to the medicine. Coronary angiography. Coronary angiography uses dye and special x rays to show the inside of your coronary arteries. To get the dye into your coronary arteries, your doctor will use a procedure called cardiac catheterization (KATH-e-ter-ih-ZA-shun). A thin, flexible tube called a catheter is put into a blood vessel in your arm, groin (upper thigh), or neck. The tube is threaded into your coronary arteries, and the dye is released into your bloodstream. Special x rays are taken while the dye is flowing through your coronary arteries. The dye lets your doctor study the flow of blood through your heart and blood vessels. This helps your doctor find blockages that can cause a heart attack. Implantable loop recorder. This device detects abnormal heart rhythms. Minor surgery is used to place this device under the skin in the chest area. An implantable loop recorder helps doctors figure out why a person may be having palpitations or fainting spells, especially if these symptoms don't happen very often. The device can be used for as long as 12 to 24 months.

### Question: What are the treatments for Atrial Fibrillation ? ### Answer:

Treatment for atrial fibrillation (AF) depends on how often you have symptoms, how severe they are, and whether you already have heart disease. General treatment options include medicines, medical procedures, and lifestyle changes. Goals of Treatment The goals of treating AF include: Preventing blood clots from forming, thus lowering the risk of stroke. Controlling how many times a minute the ventricles contract. This is called rate control. Rate control is important because it allows the ventricles enough time to completely fill with blood. With this approach, the abnormal heart rhythm continues, but you feel better and have fewer symptoms. Restoring a normal heart rhythm. This is called rhythm control. Rhythm control allows the atria and ventricles to work together to efficiently pump blood to the body. Treating any underlying disorder that's causing or raising the risk of AFfor example, hyperthyroidism (too much thyroid hormone). Who Needs Treatment for Atrial Fibrillation? People who have AF but don't have symptoms or related heart problems may not need treatment. AF may even go back to a normal heart rhythm on its own. (This also can occur in people who have AF with symptoms.) In some people who have AF for the first time, doctors may choose to use an electrical procedure or medicine to restore a normal heart rhythm. Repeat episodes of AF tend to cause changes to the heart's electrical system, leading to persistent or permanent AF. Most people who have persistent or permanent AF need treatment to control their heart rate and prevent complications. Specific Types of Treatment Blood Clot Prevention People who have AF are at increased risk for stroke. This is because blood can pool in the heart's upper chambers (the atria), causing a blood clot to form. If the clot breaks off and travels to the brain, it can cause a stroke. Preventing blood clots from forming is probably the most important part of treating AF. The benefits of this type of treatment have been proven in multiple studies. Doctors prescribe blood-thinning medicines to prevent blood clots. These medicines include warfarin (Coumadin), dabigatran, heparin, and aspirin. People taking blood-thinning medicines need regular blood tests to check how well the medicines are working. Rate Control Doctors can prescribe medicines to slow down the rate at which the ventricles are beating. These medicines help bring the heart rate to a normal level. Rate control is the recommended treatment for most patients who have AF, even though an abnormal heart rhythm continues and the heart doesn't work as well as it should. Most people feel better and can function well if their heart rates are well-controlled. Medicines used to control the heart rate include beta blockers (for example, metoprolol and atenolol), calcium channel blockers (diltiazem and verapamil), and digitalis (digoxin). Several other medicines also are available. Rhythm Control Restoring and maintaining a normal heart rhythm is a treatment approach recommended for people who aren't doing well with rate control treatment. This treatment also may be used for people who have only recently started having AF. The long-term benefits of rhythm control have not been proven conclusively yet. Doctors use medicines or procedures to control the heart's rhythm. Patients often begin rhythm control treatment in a hospital so that their hearts can be closely watched. The longer you have AF, the less likely it is that doctors can restore a normal heart rhythm. This is especially true for people who have had AF for 6 months or more. Restoring a normal rhythm also becomes less likely if the atria are enlarged or if any underlying heart disease worsens. In these cases, the chance that AF will recur is high, even if you're taking medicine to help convert AF to a normal rhythm. Medicines. Medicines used to control the heart rhythm include amiodarone, sotalol, flecainide, propafenone, dofetilide, and ibutilide. Sometimes older medicinessuch as quinidine, procainamide, and disopyramideare used. Your doctor will carefully tailor the dose and type of medicines he or she prescribes to treat your AF. This is because medicines used to treat AF can cause a different kind of arrhythmia. These medicines also can harm people who have underlying diseases of the heart or other organs. This is especially true for patients who have an unusual heart rhythm problem called Wolff-Parkinson-White syndrome. Your doctor may start you on a small dose of medicine and then gradually increase the dose until your symptoms are controlled. Medicines used for rhythm control can be given regularly by injection at a doctor's office, clinic, or hospital. Or, you may routinely take pills to try to control AF or prevent repeat episodes. If your doctor knows how you'll react to a medicine, a specific dose may be prescribed for you to take on an as-needed basis if you have an episode of AF. Procedures. Doctors use several procedures to restore a normal heart rhythm. For example, they may use electrical cardioversion to treat a fast or irregular heartbeat. For this procedure, low-energy shocks are given to your heart to trigger a normal rhythm. You're temporarily put to sleep before you receive the shocks. Electrical cardioversion isn't the same as the emergency heart shocking procedure often seen on TV programs. It's planned in advance and done under carefully controlled conditions. Before doing electrical cardioversion, your doctor may recommend transesophageal echocardiography (TEE). This test can rule out the presence of blood clots in the atria. If clots are present, you may need to take blood-thinning medicines before the procedure. These medicines can help get rid of the clots. Catheter ablation (ab-LA-shun) may be used to restore a normal heart rhythm if medicines or electrical cardioversion don't work. For this procedure, a wire is inserted through a vein in the leg or arm and threaded to the heart. Radio wave energy is sent through the wire to destroy abnormal tissue that may be disrupting the normal flow of electrical signals. An electrophysiologist usually does this procedure in a hospital. Your doctor may recommend a TEE before catheter ablation to check for blood clots in the atria. Sometimes doctors use catheter ablation to destroy the atrioventricular (AV) node. The AV node is where the heart's electrical signals pass from the atria to the ventricles (the heart's lower chambers). This procedure requires your doctor to surgically implant a device called a pacemaker, which helps maintain a normal heart rhythm. Research on the benefits of catheter ablation as a treatment for AF is still ongoing. (For more information, go to the "Clinical Trials" section of this article.) Another procedure to restore a normal heart rhythm is called maze surgery. For this procedure, the surgeon makes small cuts or burns in the atria. These cuts or burns prevent the spread of disorganized electrical signals. This procedure requires open-heart surgery, so it's usually done when a person requires heart surgery for other reasons, such as for heart valve disease (which can increase the risk of AF). Approaches To Treating Underlying Causes and Reducing Risk Factors Your doctor may recommend treatments for an underlying cause of AF or to reduce AF risk factors. For example, he or she may prescribe medicines to treat an overactive thyroid, lower high blood pressure, or manage high blood cholesterol. Your doctor also may recommend lifestyle changes, such as following a healthy diet, cutting back on salt intake (to help lower blood pressure), quitting smoking, and reducing stress. Limiting or avoiding alcohol, caffeine, or other stimulants that may increase your heart rate also can help reduce your risk for AF.

### Question: How to prevent Prostate Cancer ? ### Answer:

Key Points - Avoiding risk factors and increasing protective factors may help prevent cancer. - The following risk factors may increase the risk of prostate cancer: - Age - Family history of prostate cancer - Race - Hormones - Vitamin E - Folic acid - Dairy and calcium - The following protective factors may decrease the risk of prostate cancer: - Folate - Finasteride and Dutasteride - The following have been proven not to affect the risk of prostate cancer, or their effects on prostate cancer risk are not known: - Selenium and vitamin E - Diet - Multivitamins - Lycopene - Cancer prevention clinical trials are used to study ways to prevent cancer. - New ways to prevent prostate cancer are being studied in clinical trials. Avoiding risk factors and increasing protective factors may help prevent cancer. Avoiding cancer risk factors may help prevent certain cancers. Risk factors include smoking, being overweight, and not getting enough exercise. Increasing protective factors such as quitting smoking and exercising may also help prevent some cancers. Talk to your doctor or other health care professional about how you might lower your risk of cancer. The following risk factors may increase the risk of prostate cancer: Age Prostate cancer is rare in men younger than 50 years of age. The chance of developing prostate cancer increases as men get older. Family history of prostate cancer A man whose father, brother, or son has had prostate cancer has a higher-than-average risk of prostate cancer. Race Prostate cancer occurs more often in African-American men than in white men. African-American men with prostate cancer are more likely to die from the disease than white men with prostate cancer. Hormones The prostate needs male hormones to work the way it should. The main male sex hormone is testosterone. Testosterone helps the body develop and maintain male sex characteristics. Testosterone is changed into dihydrotestosterone (DHT) by an enzyme in the body. DHT is important for normal prostate growth but can also cause the prostate to get bigger and may play a part in the development of prostate cancer. Vitamin E The Selenium and Vitamin E Cancer Prevention Trial (SELECT) found that vitamin E taken alone increased the risk of prostate cancer. The risk continued even after the men stopped taking vitamin E. Folic acid Folate is a kind of vitamin B that occurs naturally in some foods, such as green vegetables, beans and orange juice. Folic acid is a man-made form of folate that is found in vitamin supplements and fortified foods, such as whole-grain breads and cereals. A 10-year study showed that the risk of prostate cancer was increased in men who took 1 milligram (mg) supplements of folic acid. However, the risk of prostate cancer was lower in men who had enough folate in their diets. Dairy and calcium A diet high in dairy foods and calcium may cause a small increase in the risk of prostate cancer. The following protective factors may decrease the risk of prostate cancer: Folate Folate is a kind of vitamin B that occurs naturally in some foods, such as green vegetables, beans and orange juice. Folic acid is a man-made form of folate that is found in vitamin supplements and fortified foods, such as whole-grain breads and cereals. A 10-year study showed that the risk of prostate cancer was lower in men who had enough folate in their diets. However, the risk of prostate cancer was increased in men who took 1 milligram (mg) supplements of folic acid. Finasteride and Dutasteride Finasteride and dutasteride are drugs used to lower the amount of male sex hormones made by the body. These drugs block the enzyme that changes testosterone into dihydrotestosterone (DHT). Higher than normal levels of DHT may play a part in developing prostate cancer. Taking finasteride or dutasteride has been shown to lower the risk for prostate cancer, but it is not known if these drugs lower the risk of death from prostate cancer. The Prostate Cancer Prevention Trial (PCPT) studied whether the drug finasteride can prevent prostate cancer in healthy men 55 years of age and older. This prevention study showed there were fewer prostate cancers in the group of men that took finasteride compared with the group of men that did not. Also, the men who took finasteride who did have prostate cancer had more aggressive tumors. The number of deaths from prostate cancer was the same in both groups. Men who took finasteride reported more side effects compared with the group of men that did not, including erectile dysfunction, loss of desire for sex, and enlarged breasts. The Reduction by Dutasteride of Prostate Cancer Events Trial (REDUCE) studied whether the drug dutasteride can prevent prostate cancer in men aged 50 to 75 years at higher risk for the disease. This prevention study showed there were fewer prostate cancers in the group of men who took dutasteride compared with the group of men that did not. The number of less aggressive prostate cancers was lower, but the number of more aggressive prostate cancers was not. Men who took dutasteride reported more side effects than men who did not, including erectile dysfunction, loss of desire for sex, less semen, and gynecomastia (enlarged breasts). The following have been proven not to affect the risk of prostate cancer, or their effects on prostate cancer risk are not known: Selenium and vitamin E The Selenium and Vitamin E Cancer Prevention Trial (SELECT) studied whether taking vitamin E and selenium (a mineral) will prevent prostate cancer. The selenium and vitamin E were taken separately or together by healthy men 55 years of age and older (50 years of age and older for African-American men). The study showed that taking selenium alone or selenium and vitamin E together did not decrease the risk of prostate cancer. Diet It is not known if decreasing fat or increasing fruits and vegetables in the diet helps decrease the risk of prostate cancer or death from prostate cancer. In the PCPT trial, certain fatty acids increased the risk of high-grade prostate cancer while others decreased the risk of high-grade prostate cancer. Multivitamins Regular use of multivitamins has not been proven to increase the risk of early or localized prostate cancer. However, a large study showed an increased risk of advanced prostate cancer among men who took multivitamins more than seven times a week. Lycopene Some studies have shown that a diet high in lycopene may be linked to a decreased risk of prostate cancer, but other studies have not. It has not been proven that taking lycopene supplements decreases the risk of prostate cancer. Cancer prevention clinical trials are used to study ways to prevent cancer. Cancer prevention clinical trials are used to study ways to lower the risk of developing certain types of cancer. Some cancer prevention trials are conducted with healthy people who have not had cancer but who have an increased risk for cancer. Other prevention trials are conducted with people who have had cancer and are trying to prevent another cancer of the same type or to lower their chance of developing a new type of cancer. Other trials are done with healthy volunteers who are not known to have any risk factors for cancer. The purpose of some cancer prevention clinical trials is to find out whether actions people take can prevent cancer. These may include eating fruits and vegetables, exercising, quitting smoking, or taking certain medicines, vitamins, minerals, or food supplements. New ways to prevent prostate cancer are being studied in clinical trials. Clinical trials are taking place in many parts of the country. Information about clinical trials can be found in the Clinical Trials section of the NCI website. Check NCI's list of cancer clinical trials for prostate cancer prevention trials that are accepting patients.

### Question: What are the stages of Adult Hodgkin Lymphoma ? ### Answer:

Key Points - After adult Hodgkin lymphoma has been diagnosed, tests are done to find out if cancer cells have spread within the lymph system or to other parts of the body. - There are three ways that cancer spreads in the body. - Stages of adult Hodgkin lymphoma may include A, B, E, and S. - The following stages are used for adult Hodgkin lymphoma: - Stage I - Stage II - Stage III - Stage IV - Adult Hodgkin lymphoma may be grouped for treatment as follows: - Early Favorable - Early Unfavorable - Advanced After adult Hodgkin lymphoma has been diagnosed, tests are done to find out if cancer cells have spread within the lymph system or to other parts of the body. The process used to find out if cancer has spread within the lymph system or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. The following tests and procedures may be used in the staging process: - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. For adult Hodgkin lymphoma, CT scans of the neck, chest, abdomen, and pelvis are taken. - PET-CT scan : A procedure that combines the pictures from a positron emission tomography (PET) scan and a computed tomography (CT) scan. The PET and CT scans are done at the same time on the same machine. The pictures from both scans are combined to make a more detailed picture than either test would make by itself. A PET scan is a procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. - Bone marrow aspiration and biopsy : The removal of bone marrow, blood, and a small piece of bone by inserting a hollow needle into the hipbone or breastbone. A pathologist views the bone marrow, blood, and bone under a microscope to look for signs of cancer. For pregnant women with Hodgkin lymphoma, staging tests that protect the fetus from the harms of radiation are used. These include: - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI). - Ultrasound exam: A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. There are three ways that cancer spreads in the body. Cancer can spread through tissue, the lymph system, and the blood: - Tissue. The cancer spreads from where it began by growing into nearby areas. - Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body. - Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body. Stages of adult Hodgkin lymphoma may include A, B, E, and S. Adult Hodgkin lymphoma may be described as follows: - A: The patient does not have B symptoms (fever, weight loss, or night sweats). - B: The patient has B symptoms. - E: Cancer is found in an organ or tissue that is not part of the lymph system but which may be next to an involved area of the lymph system. - S: Cancer is found in the spleen. The following stages are used for adult Hodgkin lymphoma: Stage I Stage I is divided into stage I and stage IE. - Stage I: Cancer is found in one of the following places in the lymph system: - One or more lymph nodes in one lymph node group. - Waldeyer's ring. - Thymus. - Spleen. - Stage IE: Cancer is found outside the lymph system in one organ or area. Stage II Stage II is divided into stage II and stage IIE. - Stage II: Cancer is found in two or more lymph node groups either above or below the diaphragm (the thin muscle below the lungs that helps breathing and separates the chest from the abdomen). - Stage IIE: Cancer is found in one or more lymph node groups either above or below the diaphragm and outside the lymph nodes in a nearby organ or area. Stage III Stage III is divided into stage III, stage IIIE, stage IIIS, and stage IIIE,S. - Stage III: Cancer is found in lymph node groups above and below the diaphragm (the thin muscle below the lungs that helps breathing and separates the chest from the abdomen). - Stage IIIE: Cancer is found in lymph node groups above and below the diaphragm and outside the lymph nodes in a nearby organ or area. - Stage IIIS: Cancer is found in lymph node groups above and below the diaphragm, and in the spleen. - Stage IIIE,S: Cancer is found in lymph node groups above and below the diaphragm, outside the lymph nodes in a nearby organ or area, and in the spleen. Stage IV In stage IV, the cancer: - is found outside the lymph nodes throughout one or more organs, and may be in lymph nodes near those organs; or - is found outside the lymph nodes in one organ and has spread to areas far away from that organ; or - is found in the lung, liver, bone marrow, or cerebrospinal fluid (CSF). The cancer has not spread to the lung, liver, bone marrow, or CSF from nearby areas. Adult Hodgkin lymphoma may be grouped for treatment as follows: Early Favorable Early favorable adult Hodgkin lymphoma is stage I or stage II, without risk factors. Early Unfavorable Early unfavorable adult Hodgkin lymphoma is stage I or stage II with one or more of the following risk factors: - A tumor in the chest that is larger than 1/3 of the width of the chest or at least 10 centimeters. - Cancer in an organ other than the lymph nodes. - A high sedimentation rate (in a sample of blood, the red blood cells settle to the bottom of the test tube more quickly than normal). - Three or more lymph nodes with cancer. - Symptoms such as fever, weight loss, or night sweats. Advanced Advanced Hodgkin lymphoma includes some or all of the following risk factors: - Being male. - Being aged 45 years or older. - Having stage IV disease. - Having a low blood albumin (protein) level (below 4). - Having a low hemoglobin level (below 10.5). - Having a high white blood cell count (15,000 or higher). - Having a low lymphocyte count (below 600 or less than 8% of the white blood cell count).

### Question: What are the stages of Uterine Sarcoma ? ### Answer:

Key Points - After uterine sarcoma has been diagnosed, tests are done to find out if cancer cells have spread within the uterus or to other parts of the body. - Uterine sarcoma may be diagnosed, staged, and treated in the same surgery. - There are three ways that cancer spreads in the body. - Cancer may spread from where it began to other parts of the body. - The following stages are used for uterine sarcoma: - Stage I - Stage II - Stage III - Stage IV After uterine sarcoma has been diagnosed, tests are done to find out if cancer cells have spread within the uterus or to other parts of the body. The process used to find out if cancer has spread within the uterus or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. The following procedures may be used in the staging process: - Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease. - CA 125 assay : A test that measures the level of CA 125 in the blood. CA 125 is a substance released by cells into the bloodstream. An increased CA 125 level is sometimes a sign of cancer or other condition. - Chest x-ray : An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body. - Transvaginal ultrasound exam: A procedure used to examine the vagina, uterus, fallopian tubes, and bladder. An ultrasound transducer (probe) is inserted into the vagina and used to bounce high-energy sound waves (ultrasound) off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. The doctor can identify tumors by looking at the sonogram. - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, such as the abdomen and pelvis, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues to show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - Cystoscopy : A procedure to look inside the bladder and urethra to check for abnormal areas. A cystoscope is inserted through the urethra into the bladder. A cystoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue samples, which are checked under a microscope for signs of cancer. Uterine sarcoma may be diagnosed, staged, and treated in the same surgery. Surgery is used to diagnose, stage, and treat uterine sarcoma. During this surgery, the doctor removes as much of the cancer as possible. The following procedures may be used to diagnose, stage, and treat uterine sarcoma: - Laparotomy: A surgical procedure in which an incision (cut) is made in the wall of the abdomen to check the inside of the abdomen for signs of disease. The size of the incision depends on the reason the laparotomy is being done. Sometimes organs are removed or tissue samples are taken and checked under a microscope for signs of disease. - Abdominal and pelvic washings: A procedure in which a saline solution is placed into the abdominal and pelvic body cavities. After a short time, the fluid is removed and viewed under a microscope to check for cancer cells. - Total abdominal hysterectomy: A surgical procedure to remove the uterus and cervix through a large incision (cut) in the abdomen. - Bilateral salpingo-oophorectomy: Surgery to remove both ovaries and both fallopian tubes. - Lymphadenectomy: A surgical procedure in which lymph nodes are removed and checked under a microscope for signs of cancer. For a regional lymphadenectomy, some of the lymph nodes in the tumor area are removed. For a radical lymphadenectomy, most or all of the lymph nodes in the tumor area are removed. This procedure is also called lymph node dissection. Treatment in addition to surgery may be given, as described in the Treatment Option Overview section of this summary. There are three ways that cancer spreads in the body. Cancer can spread through tissue, the lymph system, and the blood: - Tissue. The cancer spreads from where it began by growing into nearby areas. - Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body. - Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body. Cancer may spread from where it began to other parts of the body. When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood. - Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body. - Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body. The metastatic tumor is the same type of cancer as the primary tumor. For example, if uterine sarcoma spreads to the lung, the cancer cells in the lung are actually uterine sarcoma cells. The disease is metastatic uterine sarcoma, not lung cancer. The following stages are used for uterine sarcoma: Stage I In stage I, cancer is found in the uterus only. Stage I is divided into stages IA and IB, based on how far the cancer has spread. - Stage IA: Cancer is in the endometrium only or less than halfway through the myometrium (muscle layer of the uterus). - Stage IB: Cancer has spread halfway or more into the myometrium. Stage II In stage II, cancer has spread into connective tissue of the cervix, but has not spread outside the uterus. Stage III In stage III, cancer has spread beyond the uterus and cervix, but has not spread beyond the pelvis. Stage III is divided into stages IIIA, IIIB, and IIIC, based on how far the cancer has spread within the pelvis. - Stage IIIA: Cancer has spread to the outer layer of the uterus and/or to the fallopian tubes, ovaries, and ligaments of the uterus. - Stage IIIB: Cancer has spread to the vagina or to the parametrium (connective tissue and fat around the uterus). - Stage IIIC: Cancer has spread to lymph nodes in the pelvis and/or around the aorta (largest artery in the body, which carries blood away from the heart). Stage IV In stage IV, cancer has spread beyond the pelvis. Stage IV is divided into stages IVA and IVB, based on how far the cancer has spread. - Stage IVA: Cancer has spread to the bladder and/or bowel wall. - Stage IVB: Cancer has spread to other parts of the body beyond the pelvis, including the abdomen and/or lymph nodes in the groin.

### Question: What are the stages of Laryngeal Cancer ? ### Answer:

Key Points - After laryngeal cancer has been diagnosed, tests are done to find out if cancer cells have spread within the larynx or to other parts of the body. - There are three ways that cancer spreads in the body. - Cancer may spread from where it began to other parts of the body. - The following stages are used for laryngeal cancer: - Stage 0 (Carcinoma in Situ) - Stage I - Stage II - Stage III - Stage IV After laryngeal cancer has been diagnosed, tests are done to find out if cancer cells have spread within the larynx or to other parts of the body. The process used to find out if cancer has spread within the larynx or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage of the disease in order to plan treatment. The results of some of the tests used to diagnose laryngeal cancer are often also used to stage the disease. There are three ways that cancer spreads in the body.

The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body. - Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body. The metastatic tumor is the same type of cancer as the primary tumor. For example, if laryngeal cancer spreads to the lung, the cancer cells in the lung are actually laryngeal cancer cells. The disease is metastatic laryngeal cancer, not lung cancer. The following stages are used for laryngeal cancer: Stage 0 (Carcinoma in Situ) In stage 0, abnormal cells are found in the lining of the larynx. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ. Stage I In stage I, cancer has formed. Stage I laryngeal cancer depends on where cancer began in the larynx: - Supraglottis: Cancer is in one area of the supraglottis only and the vocal cords can move normally. - Glottis: Cancer is in one or both vocal cords and the vocal cords can move normally. - Subglottis: Cancer is in the subglottis only. Stage II In stage II, cancer is in the larynx only. Stage II laryngeal cancer depends on where cancer began in the larynx: - Supraglottis: Cancer is in more than one area of the supraglottis or surrounding tissues. - Glottis: Cancer has spread to the supraglottis and/or the subglottis and/or the vocal cords cannot move normally. - Subglottis: Cancer has spread to one or both vocal cords, which may not move normally. Stage III Stage III laryngeal cancer depends on whether cancer has spread from the supraglottis, glottis, or subglottis. In stage III cancer of the supraglottis: - cancer is in the larynx only and the vocal cords cannot move, and/or cancer is in tissues next to the larynx. Cancer may have spread to one lymph node on the same side of the neck as the original tumor and the lymph node is 3 centimeters or smaller; or - cancer is in one area of the supraglottis and in one lymph node on the same side of the neck as the original tumor; the lymph node is 3 centimeters or smaller and the vocal cords can move normally; or - cancer is in more than one area of the supraglottis or surrounding tissues and in one lymph node on the same side of the neck as the original tumor; the lymph node is 3 centimeters or smaller. In stage III cancer of the glottis: - cancer is in the larynx only and the vocal cords cannot move, and/or cancer is in tissues next to the larynx; cancer may have spread to one lymph node on the same side of the neck as the original tumor and the lymph node is 3 centimeters or smaller; or - cancer is in one or both vocal cords and in one lymph node on the same side of the neck as the original tumor; the lymph node is 3 centimeters or smaller and the vocal cords can move normally; or - cancer has spread to the supraglottis and/or the subglottis and/or the vocal cords cannot move normally. Cancer has also spread to one lymph node on the same side of the neck as the original tumor and the lymph node is 3 centimeters or smaller. In stage III cancer of the subglottis: - cancer is in the larynx and the vocal cords cannot move; cancer may have spread to one lymph node on the same side of the neck as the original tumor and the lymph node is 3 centimeters or smaller; or - cancer is in the subglottis and in one lymph node on the same side of the neck as the original tumor; the lymph node is 3 centimeters or smaller; or - cancer has spread to one or both vocal cords, which may not move normally. Cancer has also spread to one lymph node on the same side of the neck as the original tumor and the lymph node is 3 centimeters or smaller. Stage IV Stage IV is divided into stage IVA, stage IVB, and stage IVC. Each substage is the same for cancer in the supraglottis, glottis, or subglottis. - In stage IVA: - cancer has spread through the thyroid cartilage and/or has spread to tissues beyond the larynx such as the neck, trachea, thyroid, or esophagus. Cancer may have spread to one lymph node on the same side of the neck as the original tumor and the lymph node is 3 centimeters or smaller; or - cancer has spread to one lymph node on the same side of the neck as the original tumor and the lymph node is larger than 3 centimeters but not larger than 6 centimeters, or has spread to more than one lymph node anywhere in the neck with none larger than 6 centimeters. Cancer may have spread to tissues beyond the larynx, such as the neck, trachea, thyroid, or esophagus. The vocal cords may not move normally. - In stage IVB: - cancer has spread to the space in front of the spinal column, surrounds the carotid artery, or has spread to parts of the chest. Cancer may have spread to one or more lymph nodes anywhere in the neck and the lymph nodes may be any size; or - cancer has spread to a lymph node that is larger than 6 centimeters and may have spread as far as the space in front of the spinal column, around the carotid artery, or to parts of the chest. The vocal cords may not move normally. - In stage IVC, cancer has spread to other parts of the body, such as the lungs, liver, or bone.

### Question: What are the stages of Melanoma ? ### Answer:

Key Points - After melanoma has been diagnosed, tests are done to find out if cancer cells have spread within the skin or to other parts of the body. - There are three ways that cancer spreads in the body. - Cancer may spread from where it began to other parts of the body. - The method used to stage melanoma is based mainly on the thickness of the tumor and whether cancer has spread to lymph nodes or other parts of the body. - The following stages are used for melanoma: - Stage 0 (Melanoma in Situ) - Stage I - Stage II - Stage III - Stage IV After melanoma has been diagnosed, tests are done to find out if cancer cells have spread within the skin or to other parts of the body. The process used to find out whether cancer has spread within the skin or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. The following tests and procedures may be used in the staging process: - Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patients health habits and past illnesses and treatments will also be taken. - Lymph node mapping and sentinel lymph node biopsy : Procedures in which a radioactive substance and/or blue dye is injected near the tumor. The substance or dye flows through lymph ducts to the sentinel node or nodes (the first lymph node or nodes where cancer cells are likely to spread). The surgeon removes only the nodes with the radioactive substance or dye. A pathologist views a sample of tissue under a microscope to check for cancer cells. If no cancer cells are found, it may not be necessary to remove more nodes. - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. For melanoma, pictures may be taken of the chest, abdomen, and pelvis. - PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. - MRI (magnetic resonance imaging) with gadolinium : A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body, such as the brain. A substance called gadolinium is injected into a vein. The gadolinium collects around the cancer cells so they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI). - Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. For melanoma, the blood is checked for an enzyme called lactate dehydrogenase (LDH). LDH levels that are higher than normal may be a sign of melanoma. The results of these tests are viewed together with the results of the tumor biopsy to find out the stage of the melanoma. There are three ways that cancer spreads in the body. Cancer can spread through tissue, the lymph system, and the blood: - Tissue. The cancer spreads from where it began by growing into nearby areas. - Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body. - Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body. Cancer may spread from where it began to other parts of the body. When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood. - Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body. - Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body. The metastatic tumor is the same type of cancer as the primary tumor. For example, if melanoma spreads to the lung, the cancer cells in the lung are actually melanoma cells. The disease is metastatic melanoma, not lung cancer. The method used to stage melanoma is based mainly on the thickness of the tumor and whether cancer has spread to lymph nodes or other parts of the body. The staging of melanoma depends on the following: - The thickness of the tumor. The thickness is described using the Breslow scale. - Whether the tumor is ulcerated (has broken through the skin). - Whether the tumor has spread to the lymph nodes and if the lymph nodes are joined together (matted). - Whether the tumor has spread to other parts of the body. The following stages are used for melanoma: Stage 0 (Melanoma in Situ) In stage 0, abnormal melanocytes are found in the epidermis. These abnormal melanocytes may become cancer and spread into nearby normal tissue. Stage 0 is also called melanoma in situ. Stage I In stage I, cancer has formed. Stage I is divided into stages IA and IB. - Stage IA: In stage IA, the tumor is not more than 1 millimeter thick, with no ulceration. - Stage IB: In stage IB, the tumor is either: - not more than 1 millimeter thick and it has ulceration; or - more than 1 but not more than 2 millimeters thick, with no ulceration. Stage II Stage II is divided into stages IIA, IIB, and IIC. - Stage IIA: In stage IIA, the tumor is either: - more than 1 but not more than 2 millimeters thick, with ulceration; or - more than 2 but not more than 4 millimeters thick, with no ulceration. - Stage IIB: In stage IIB, the tumor is either: - more than 2 but not more than 4 millimeters thick, with ulceration; or - more than 4 millimeters thick, with no ulceration. - Stage IIC: In stage IIC, the tumor is more than 4 millimeters thick, with ulceration. Stage III In stage III, the tumor may be any thickness, with or without ulceration. One or more of the following is true: - Cancer has spread to one or more lymph nodes. - Lymph nodes are joined together (matted). - Cancer is in a lymph vessel between the primary tumor and nearby lymph nodes. The cancer is more than 2 centimeters away from the primary tumor. - Very small tumors are found on or under the skin, not more than 2 centimeters away from the primary tumor. Stage IV In stage IV, the cancer has spread to other places in the body, such as the lung, liver, brain, bone, soft tissue, or gastrointestinal (GI) tract. Cancer may have spread to places in the skin far away from where it first started.

### Question: What are the treatments for Diabetic Neuropathies: The Nerve Damage of Diabetes ? ### Answer:

The first treatment step is to bring blood glucose levels within the normal range to help prevent further nerve damage. Blood glucose monitoring, meal planning, physical activity, and diabetes medicines or insulin will help control blood glucose levels. Symptoms may get worse when blood glucose is first brought under control, but over time, maintaining lower blood glucose levels helps lessen symptoms. Good blood glucose control may also help prevent or delay the onset of further problems. As scientists learn more about the underlying causes of neuropathy, new treatments may become available to help slow, prevent, or even reverse nerve damage. As described in the following sections, additional treatment depends on the type of nerve problem and symptom. Pain Relief Doctors usually treat painful diabetic neuropathy with oral medications, although other types of treatments may help some people. People with severe nerve pain may benefit from a combination of medications or treatments and should consider talking with a health care provider about treatment options. Medications used to help relieve diabetic nerve pain include - tricyclic antidepressants, such as amitriptyline, imipramine, and desipramine (Norpramin, Pertofrane) - other types of antidepressants, such as duloxetine (Cymbalta), venlafaxine, bupropion (Wellbutrin), paroxetine (Paxil), and citalopram (Celexa) - anticonvulsants, such as pregabalin (Lyrica), gabapentin (Gabarone, Neurontin), carbamazepine, and lamotrigine (Lamictal) - opioids and opioidlike drugs, such as controlled-release oxycodone, an opioid; and tramadol (Ultram), an opioid that also acts as an antidepressant Duloxetine and pregabalin are approved by the U.S. Food and Drug Administration specifically for treating painful diabetic peripheral neuropathy. People do not have to be depressed for an antidepressant to help relieve their nerve pain. All medications have side effects, and some are not recommended for use in older adults or those with heart disease. Because over-the-counter pain medicines such as acetaminophen and ibuprofen may not work well for treating most nerve pain and can have serious side effects, some experts recommend avoiding these medications. Treatments that are applied to the skintypically to the feetinclude capsaicin cream and lidocaine patches (Lidoderm, Lidopain). Studies suggest that nitrate sprays or patches for the feet may relieve pain. Studies of alpha-lipoic acid, an antioxidant, and evening primrose oil suggest they may help relieve symptoms and improve nerve function in some patients. A device called a bed cradle can keep sheets and blankets from touching sensitive feet and legs. Acupuncture, biofeedback, or physical therapy may help relieve pain in some people. Treatments that involve electrical nerve stimulation, magnetic therapy, and laser or light therapy may be helpful but need further study. Researchers are also studying several new therapies in clinical trials. Gastrointestinal Problems To relieve mild symptoms of gastroparesisindigestion, belching, nausea, or vomitingdoctors suggest eating small, frequent meals; avoiding fats; and eating less fiber. When symptoms are severe, doctors may prescribe erythromycin to speed digestion, metoclopramide to speed digestion and help relieve nausea, or other medications to help regulate digestion or reduce stomach acid secretion. To relieve diarrhea or other bowel problems, doctors may prescribe an antibiotic such as tetracycline, or other medications as appropriate. Dizziness and Weakness Sitting or standing slowly may help prevent the light-headedness, dizziness, or fainting associated with blood pressure and circulation problems. Raising the head of the bed or wearing elastic stockings may also help. Some people benefit from increased salt in the diet and treatment with salt-retaining hormones. Others benefit from high blood pressure medications. Physical therapy can help when muscle weakness or loss of coordination is a problem. Urinary and Sexual Problems To clear up a urinary tract infection, the doctor will probably prescribe an antibiotic. Drinking plenty of fluids will help prevent another infection. People who have incontinence should try to urinate at regular intervalsevery 3 hours, for examplebecause they may not be able to tell when the bladder is full. To treat erectile dysfunction in men, the doctor will first do tests to rule out a hormonal cause. Several methods are available to treat erectile dysfunction caused by neuropathy. Medicines are available to help men have and maintain erections by increasing blood flow to the penis. Some are oral medications and others are injected into the penis or inserted into the urethra at the tip of the penis. Mechanical vacuum devices can also increase blood flow to the penis. Another option is to surgically implant an inflatable or semirigid device in the penis. Vaginal lubricants may be useful for women when neuropathy causes vaginal dryness. To treat problems with arousal and orgasm, the doctor may refer women to a gynecologist. Foot Care People with neuropathy need to take special care of their feet. The nerves to the feet are the longest in the body and are the ones most often affected by neuropathy. Loss of sensation in the feet means that sores or injuries may not be noticed and may become ulcerated or infected. Circulation problems also increase the risk of foot ulcers. Smoking increases the risk of foot problems and amputation. A health care provider may be able to provide help with quitting smoking. More than 60 percent of all nontraumatic lower-limb amputations in the United States occur in people with diabetes. Nontraumatic amputations are those not caused by trauma such as severe injuries from an accident. In 2004, about 71,000 nontraumatic amputations were performed in people with diabetes. Comprehensive foot care programs can reduce amputation rates by 45 to 85 percent. Careful foot care involves - cleaning the feet daily using warmnot hotwater and a mild soap. Soaking the feet should be avoided. A soft towel can be used to dry the feet and between the toes. - inspecting the feet and toes every day for cuts, blisters, redness, swelling, calluses, or other problems. Using a mirrorhandheld or placed on the floormay be helpful in checking the bottoms of the feet, or another person can help check the feet. A health care provider should be notified of any problems. - using lotion to moisturize the feet. Getting lotion between the toes should be avoided. - filing corns and calluses gently with a pumice stone after a bath or shower. - cutting toenails to the shape of the toes and filing the edges with an emery board each week or when needed. - always wearing shoes or slippers to protect feet from injuries. Wearing thick, soft, seamless socks can prevent skin irritation. - wearing shoes that fit well and allow the toes to move. New shoes can be broken in gradually by first wearing them for only an hour at a time. - looking shoes over carefully before putting them on and feeling the insides to make sure the shoes are free of tears, sharp edges, or objects that might injure the feet. People who need help taking care of their feet should consider making an appointment to see a foot doctor, also called a podiatrist.

### Question: What are the treatments for Hypoglycemia ? ### Answer:

Signs and symptoms of hypoglycemia vary from person to person. People with diabetes should get to know their signs and symptoms and describe them to their friends and family so they can help if needed. School staff should be told how to recognize a child's signs and symptoms of hypoglycemia and how to treat it. People who experience hypoglycemia several times in a week should call their health care provider. They may need a change in their treatment plan: less medication or a different medication, a new schedule for insulin or medication, a different meal plan, or a new physical activity plan. Prompt Treatment for Hypoglycemia When people think their blood glucose is too low, they should check the blood glucose level of a blood sample using a meter. If the level is below 70 mg/dL, one of these quick-fix foods should be consumed right away to raise blood glucose: - 3 or 4 glucose tablets - 1 serving of glucose gelthe amount equal to 15 grams of carbohydrate - 1/2 cup, or 4 ounces, of any fruit juice - 1/2 cup, or 4 ounces, of a regularnot dietsoft drink - 1 cup, or 8 ounces, of milk - 5 or 6 pieces of hard candy - 1 tablespoon of sugar or honey Recommended amounts may be less for small children. The child's doctor can advise about the right amount to give a child. The next step is to recheck blood glucose in 15 minutes to make sure it is 70 mg/dL or above. If it's still too low, another serving of a quick-fix food should be eaten. These steps should be repeated until the blood glucose level is 70 mg/dL or above. If the next meal is an hour or more away, a snack should be eaten once the quick-fix foods have raised the blood glucose level to 70 mg/dL or above. For People Who Take Acarbose (Precose) or Miglitol (Glyset) People who take either of these diabetes medications should know that only pure glucose, also called dextroseavailable in tablet or gel formwill raise their blood glucose level during a low blood glucose episode. Other quick-fix foods and drinks won't raise the level quickly enough because acarbose and miglitol slow the digestion of other forms of carbohydrate. Help from Others for Severe Hypoglycemia Severe hypoglycemiavery low blood glucosecan cause a person to pass out and can even be life threatening. Severe hypoglycemia is more likely to occur in people with type 1 diabetes. People should ask a health care provider what to do about severe hypoglycemia. Another person can help someone who has passed out by giving an injection of glucagon. Glucagon will rapidly bring the blood glucose level back to normal and help the person regain consciousness. A health care provider can prescribe a glucagon emergency kit. Family, friends, or coworkersthe people who will be around the person at risk of hypoglycemiacan learn how to give a glucagon injection and when to call 911 or get medical help. Physical Activity and Blood Glucose Levels Physical activity has many benefits for people with diabetes, including lowering blood glucose levels. However, physical activity can make levels too low and can cause hypoglycemia up to 24 hours afterward. A health care provider can advise about checking the blood glucose level before exercise. For those who take insulin or one of the oral medications that increase insulin production, the health care provider may suggest having a snack if the glucose level is below 100 mg/dL or adjusting medication doses before physical activity to help avoid hypoglycemia. A snack can prevent hypoglycemia. The health care provider may suggest extra blood glucose checks, especially after strenuous exercise. Hypoglycemia When Driving Hypoglycemia is particularly dangerous if it happens to someone who is driving. People with hypoglycemia may have trouble concentrating or seeing clearly behind the wheel and may not be able to react quickly to road hazards or to the actions of other drivers. To prevent problems, people at risk for hypoglycemia should check their blood glucose level before driving. During longer trips, they should check their blood glucose level frequently and eat snacks as needed to keep the level at 70 mg/dL or above. If necessary, they should stop for treatment and then make sure their blood glucose level is 70 mg/dL or above before starting to drive again. Hypoglycemia Unawareness Some people with diabetes do not have early warning signs of low blood glucose, a condition called hypoglycemia unawareness. This condition occurs most often in people with type 1 diabetes, but it can also occur in people with type 2 diabetes. People with hypoglycemia unawareness may need to check their blood glucose level more often so they know when hypoglycemia is about to occur. They also may need a change in their medications, meal plan, or physical activity routine. Hypoglycemia unawareness develops when frequent episodes of hypoglycemia lead to changes in how the body reacts to low blood glucose levels. The body stops releasing the hormone epinephrine and other stress hormones when blood glucose drops too low. The loss of the body's ability to release stress hormones after repeated episodes of hypoglycemia is called hypoglycemia-associated autonomic failure, or HAAF. Epinephrine causes early warning symptoms of hypoglycemia such as shakiness, sweating, anxiety, and hunger. Without the release of epinephrine and the symptoms it causes, a person may not realize that hypoglycemia is occurring and may not take action to treat it. A vicious cycle can occur in which frequent hypoglycemia leads to hypoglycemia unawareness and HAAF, which in turn leads to even more severe and dangerous hypoglycemia. Studies have shown that preventing hypoglycemia for a period as short as several weeks can sometimes break this cycle and restore awareness of symptoms. Health care providers may therefore advise people who have had severe hypoglycemia to aim for higher-than-usual blood glucose targets for short-term periods. Being Prepared for Hypoglycemia People who use insulin or take an oral diabetes medication that can cause low blood glucose should always be prepared to prevent and treat low blood glucose by - learning what can trigger low blood glucose levels - having their blood glucose meter available to test glucose levels; frequent testing may be critical for those with hypoglycemia unawareness, particularly before driving a car or engaging in any hazardous activity - always having several servings of quick-fix foods or drinks handy - wearing a medical identification bracelet or necklace - planning what to do if they develop severe hypoglycemia - telling their family, friends, and coworkers about the symptoms of hypoglycemia and how they can help if needed Normal and Target Blood Glucose Ranges Normal Blood Glucose Levels in People Who Do Not Have Diabetes Upon wakingfasting 70 to 99 mg/dL After meals 70 to 140 mg/dL Target Blood Glucose Levels in People Who Have Diabetes Before meals 70 to 130 mg/dL 1 to 2 hours after the start of a meal below 180 mg/dL For people with diabetes, a blood glucose level below 70 mg/dL is considered hypoglycemia.

### Question: How to prevent Skin Cancer ? ### Answer:

Key Points - Avoiding risk factors and increasing protective factors may help prevent cancer. - Being exposed to ultraviolet radiation is a risk factor for skin cancer. - It is not known if the following lower the risk of nonmelanoma skin cancer: - Sunscreen use and avoiding sun exposure - Chemopreventive agents - It is not known if the following lower the risk of melanoma: - Sunscreen - Counseling and protecting the skin from the sun - Cancer prevention clinical trials are used to study ways to prevent cancer. - New ways to prevent skin cancer are being studied in clinical trials. Avoiding risk factors and increasing protective factors may help prevent cancer. Avoiding cancer risk factors may help prevent certain cancers. Risk factors include smoking, being overweight, and not getting enough exercise. Increasing protective factors such as quitting smoking and exercising may also help prevent some cancers. Talk to your doctor or other health care professional about how you might lower your risk of cancer. Being exposed to ultraviolet radiation is a risk factor for skin cancer. Some studies suggest that being exposed to ultraviolet (UV) radiation and the sensitivity of a persons skin to UV radiation are risk factors for skin cancer. UV radiation is the name for the invisible rays that are part of the energy that comes from the sun. Sunlamps and tanning beds also give off UV radiation. Risk factors for nonmelanoma and melanoma cancers are not the same. - Risk factors for nonmelanoma skin cancer: - Being exposed to natural sunlight or artificial sunlight (such as from tanning beds) over long periods of time. - Having a fair complexion, which includes the following: - Fair skin that freckles and burns easily, does not tan, or tans poorly. - Blue or green or other light-colored eyes. - Red or blond hair. - Having actinic keratosis. - Past treatment with radiation. - Having a weakened immune system. - Being exposed to arsenic. - Risk factors for melanoma skin cancer: - Having a fair complexion, which includes the following: - Fair skin that freckles and burns easily, does not tan, or tans poorly. - Blue or green or other light-colored eyes. - Red or blond hair. - Being exposed to natural sunlight or artificial sunlight (such as from tanning beds) over long periods of time. - Having a history of many blistering sunburns, especially as a child or teenager. - Having several large or many small moles. - Having a family history of unusual moles (atypical nevus syndrome). - Having a family or personal history of melanoma. - Being white. It is not known if the following lower the risk of nonmelanoma skin cancer: Sunscreen use and avoiding sun exposure It is not known if nonmelanoma skin cancer risk is decreased by staying out of the sun, using sunscreens, or wearing protective clothing when outdoors. This is because not enough studies have been done to prove this. Sunscreen may help decrease the amount of UV radiation to the skin. One study found that wearing sunscreen can help prevent actinic keratoses, scaly patches of skin that sometimes become squamous cell carcinoma. The harms of using sunscreen are likely to be small and include allergic reactions to skin creams and lower levels of vitamin D made in the skin because of less sun exposure. It is also possible that when a person uses sunscreen to avoid sunburn they may spend too much time in the sun and be exposed to harmful UV radiation. Although protecting the skin and eyes from the sun has not been proven to lower the chance of getting skin cancer, skin experts suggest the following: - Use sunscreen that protects against UV radiation. - Do not stay out in the sun for long periods of time, especially when the sun is at its strongest. - Wear long sleeve shirts, long pants, sun hats, and sunglasses, when outdoors. Chemopreventive agents Chemoprevention is the use of drugs, vitamins, or other agents to try to reduce the risk of cancer. The following chemopreventive agents have been studied to find whether they lower the risk of nonmelanoma skin cancer: Beta carotene Studies of beta carotene (taken as a supplement in pills) have not shown that it prevents nonmelanoma skin cancer from forming or coming back. Isotretinoin High doses of isotretinoin have been shown to prevent new skin cancers in patients with xeroderma pigmentosum. However, isotretinoin has not been shown to prevent nonmelanoma skin cancers from coming back in patients previously treated for nonmelanoma skin cancers. Treatment with isotretinoin can cause serious side effects. Selenium Studies have shown that selenium (taken in brewer's yeast tablets) does not lower the risk of basal cell carcinoma, and may increase the risk of squamous cell carcinoma. Celecoxib A study of celecoxib in patients with actinic keratosis and a history of nonmelanoma skin cancer found those who took celecoxib had slightly lower rates of recurrent nonmelanoma skin cancers. Celecoxib may have serious side effects on the heart and blood vessels. Alpha-difluoromethylornithine (DFMO) A study of alpha-difluoromethylornithine (DFMO) in patients with a history of nonmelanoma skin cancer showed that those who took DFMO had lower rates of nonmelanoma skin cancers coming back than those who took a placebo. DFMO may cause hearing loss which is usually temporary. Nicotinamide (vitamin B3) Studies have shown that nicotinamide (vitamin B3) helps prevent new actinic keratoses lesions from forming in people who had four or fewer actinic lesions before taking nicotinamide. More studies are needed to find out if nicotinamide prevents nonmelanoma skin cancer from forming or coming back. It is not known if the following lower the risk of melanoma: Sunscreen It has not been proven that using sunscreen to prevent sunburn can protect against melanoma caused by UV radiation. Other risk factors such as having skin that burns easily, having a large number of benign moles, or having atypical nevi may also play a role in whether melanoma forms. Counseling and protecting the skin from the sun It is not known if people who receive counseling or information about avoiding sun exposure make changes in their behavior to protect their skin from the sun. Cancer prevention clinical trials are used to study ways to prevent cancer. Cancer prevention clinical trials are used to study ways to lower the risk of developing certain types of cancer. Some cancer prevention trials are conducted with healthy people who have not had cancer but who have an increased risk for cancer. Other prevention trials are conducted with people who have had cancer and are trying to prevent another cancer of the same type or to lower their chance of developing a new type of cancer. Other trials are done with healthy volunteers who are not known to have any risk factors for cancer. The purpose of some cancer prevention clinical trials is to find out whether actions people take can prevent cancer. These may include eating fruits and vegetables, exercising, quitting smoking, or taking certain medicines, vitamins, minerals, or food supplements. New ways to prevent skin cancer are being studied in clinical trials. Clinical trials are taking place in many parts of the country. Information about clinical trials can be found in the Clinical Trials section of the NCI Web site. Check NCI's list of cancer clinical trials for nonmelanoma skin cancer prevention trials and melanoma prevention trials that are now accepting patients.

### Question: What to do for Fecal Incontinence ? ### Answer:

Dietary changes that may improve fecal incontinence include - Eating the right amount of fiber. Fiber can help with diarrhea and constipation. Fiber is found in fruits, vegetables, whole grains, and beans. Fiber supplements sold in a pharmacy or in a health food store are another common source of fiber to treat fecal incontinence. The Academy of Nutrition and Dietetics recommends consuming 20 to 35 grams of fiber a day for adults and age plus five grams for children. A 7-year-old child, for example, should get 7 plus five, or 12, grams of fiber a day. American adults consume only 15 grams a day on average.2 Fiber should be added to the diet slowly to avoid bloating. - Getting plenty to drink. Drinking eight 8-ounce glasses of liquid a day may help prevent constipation. Water is a good choice. Drinks with caffeine, alcohol, milk, or carbonation should be avoided if they trigger diarrhea. Keeping a Food Diary A food diary can help identify foods that cause diarrhea and increase the risk of fecal incontinence. A food diary should list foods eaten, portion size, and when fecal incontinence occurs. After a few days, the diary may show a link between certain foods and fecal incontinence. Eating less of foods linked to fecal incontinence may improve symptoms. A food diary can also be helpful to a health care provider treating a person with fecal incontinence. Common foods and drinks linked to fecal incontinence include - dairy products such as milk, cheese, and ice cream - drinks and foods containing caffeine - cured or smoked meat such as sausage, ham, and turkey - spicy foods - alcoholic beverages - fruits such as apples, peaches, and pears - fatty and greasy foods - sweeteners in diet drinks and sugarless gum and candy, including sorbitol, xylitol, mannitol, and fructose Examples of Foods That Have Fiber Beans, cereals, and breads Fiber cup of beans (navy, pinto, kidney, etc.), cooked 6.29.6 grams cup of shredded wheat, ready-to-eat cereal 2.73.8 grams cup of 100% bran, ready-to-eat cereal 9.1 grams 1 small oat bran muffin 3.0 grams 1 whole-wheat English muffin 4.4 grams Fruits 1 small apple, with skin 3.6 grams 1 medium pear, with skin 5.5 grams cup of raspberries 4.0 grams cup of stewed prunes 3.8 grams Vegetables cup of winter squash, cooked 2.9 grams 1 medium sweet potato, baked in skin 3.8 grams cup of green peas, cooked 3.54.4 grams 1 small potato, baked, with skin 3.0 grams cup of mixed vegetables, cooked 4.0 grams cup of broccoli, cooked 2.62.8 grams cup of greens (spinach, collards, turnip greens), cooked 2.53.5 grams Medications If diarrhea is causing fecal incontinence, medication may help. Health care providers sometimes recommend using bulk laxatives, such as Citrucel and Metamucil, to develop more solid stools that are easier to control. Antidiarrheal medications such as loperamide or diphenoxylate may be recommended to slow down the bowels and help control the problem. Bowel Training Developing a regular bowel movement pattern can improve fecal incontinence, especially fecal incontinence due to constipation. Bowel training involves trying to have bowel movements at specific times of the day, such as after every meal. Over time, the body becomes used to a regular bowel movement pattern, thus reducing constipation and related fecal incontinence. Persistence is key to successful bowel training. Achieving a regular bowel control pattern can take weeks to months. Pelvic Floor Exercises and Biofeedback Exercises that strengthen the pelvic floor muscles may improve bowel control. Pelvic floor exercises involve squeezing and relaxing pelvic floor muscles 50 to 100 times a day. A health care provider can help with proper technique. Biofeedback therapy may also help a person perform the exercises properly. This therapy also improves a persons awareness of sensations in the rectum, teaching how to coordinate squeezing of the external sphincter muscle with the sensation of rectal filling. Biofeedback training uses special sensors to measure bodily functions. Sensors include pressure or EMG sensors in the anus, pressure sensors in the rectum, and a balloon in the rectum to produce graded sensations of rectal fullness. The measurements are displayed on a video screen as sounds or line graphs. The health care provider uses the information to help the person modify or change abnormal function. The person practices the exercises at home. Success with pelvic floor exercises depends on the cause of fecal incontinence, its severity, and the persons motivation and ability to follow the health care providers recommendations. Surgery Surgery may be an option for fecal incontinence that fails to improve with other treatments or for fecal incontinence caused by pelvic floor or anal sphincter muscle injuries. - Sphincteroplasty, the most common fecal incontinence surgery, reconnects the separated ends of a sphincter muscle torn by childbirth or another injury. Sphincteroplasty is performed at a hospital by a colorectal, gynecological, or general surgeon. - Artificial anal sphincter involves placing an inflatable cuff around the anus and implanting a small pump beneath the skin that the person activates to inflate or deflate the cuff. This surgery is much less common and is performed at a hospital by a specially trained colorectal surgeon. - Nonabsorbable bulking agents can be injected into the wall of the anus to bulk up the tissue around the anus. The bulkier tissues make the opening of the anus narrower so the sphincters are able to close better. The procedure is performed in a health care providers office; anesthesia is not needed. The person can return to normal physical activities 1 week after the procedure. - Bowel diversion is an operation that reroutes the normal movement of stool out of the body when part of the bowel is removed. The operation diverts the lower part of the small intestine or colon to an opening in the wall of the abdomenthe area between the chest and hips. An external pouch is attached to the opening to collect stool. The procedure is performed by a surgeon in a hospital and anesthesia is used. More information about these procedures can be found in the Bowel Diversion fact sheet. Electrical Stimulation Electrical stimulation, also called sacral nerve stimulation or neuromodulation, involves placing electrodes in the sacral nerves to the anus and rectum and continuously stimulating the nerves with electrical pulses. The sacral nerves connect to the part of the spine in the hip area. A battery-operated stimulator is placed beneath the skin. Based on the persons response, the health care provider can adjust the amount of stimulation so it works best for that person. The person can turn the stimulator on or off at any time. The procedure is performed in an outpatient center using local anesthesia.

### Question: What are the stages of AIDS-Related Lymphoma ? ### Answer:

Key Points - After AIDS-related lymphoma has been diagnosed, tests are done to find out if cancer cells have spread within the lymph system or to other parts of the body. - There are three ways that cancer spreads in the body. - Stages of AIDS-related lymphoma may include E and S. - The following stages are used for AIDS-related lymphoma: - Stage I - Stage II - Stage III - Stage IV - For treatment, AIDS-related lymphomas are grouped based on where they started in the body, as follows: - Peripheral/systemic lymphoma - Primary CNS lymphoma After AIDS-related lymphoma has been diagnosed, tests are done to find out if cancer cells have spread within the lymph system or to other parts of the body. The process used to find out if cancer cells have spread within the lymph system or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment, but AIDS-related lymphoma is usually advanced when it is diagnosed. The following tests and procedures may be used in the staging process: - Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease. The blood sample will be checked for the level of LDH (lactate dehydrogenase). - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, such as the lung, lymph nodes, and liver, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. - MRI (magnetic resonance imaging) with gadolinium : A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. A substance called gadolinium is injected into the patient through a vein. The gadolinium collects around the cancer cells so they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI). - Lumbar puncture : A procedure used to collect cerebrospinal fluid (CSF) from the spinal column. This is done by placing a needle between two bones in the spine and into the CSF around the spinal cord and removing a sample of the fluid. The sample of CSF is checked under a microscope for signs that the cancer has spread to the brain and spinal cord. The sample may also be checked for Epstein-Barr virus. This procedure is also called an LP or spinal tap. There are three ways that cancer spreads in the body. Cancer can spread through tissue, the lymph system, and the blood: - Tissue. The cancer spreads from where it began by growing into nearby areas. - Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body. - Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body. Stages of AIDS-related lymphoma may include E and S. AIDS-related lymphoma may be described as follows: - E: "E" stands for extranodal and means the cancer is found in an area or organ other than the lymph nodes or has spread to tissues beyond, but near, the major lymphatic areas. - S: "S" stands for spleen and means the cancer is found in the spleen. The following stages are used for AIDS-related lymphoma: Stage I Stage I AIDS-related lymphoma is divided into stage I and stage IE. - Stage I: Cancer is found in one lymphatic area (lymph node group, tonsils and nearby tissue, thymus, or spleen). - Stage IE: Cancer is found in one organ or area outside the lymph nodes. Stage II Stage II AIDS-related lymphoma is divided into stage II and stage IIE. - Stage II: Cancer is found in two or more lymph node groups either above or below the diaphragm (the thin muscle below the lungs that helps breathing and separates the chest from the abdomen). - Stage IIE: Cancer is found in one or more lymph node groups either above or below the diaphragm. Cancer is also found outside the lymph nodes in one organ or area on the same side of the diaphragm as the affected lymph nodes. Stage III Stage III AIDS-related lymphoma is divided into stage III, stage IIIE, stage IIIS, and stage IIIE+S. - Stage III: Cancer is found in lymph node groups above and below the diaphragm (the thin muscle below the lungs that helps breathing and separates the chest from the abdomen). - Stage IIIE: Cancer is found in lymph node groups above and below the diaphragm and outside the lymph nodes in a nearby organ or area. - Stage IIIS: Cancer is found in lymph node groups above and below the diaphragm, and in the spleen. - Stage IIIE+S: Cancer is found in lymph node groups above and below the diaphragm, outside the lymph nodes in a nearby organ or area, and in the spleen. Stage IV In stage IV AIDS-related lymphoma, the cancer: - is found throughout one or more organs that are not part of a lymphatic area (lymph node group, tonsils and nearby tissue, thymus, or spleen) and may be in lymph nodes near those organs; or - is found in one organ that is not part of a lymphatic area and has spread to organs or lymph nodes far away from that organ; or - is found in the liver, bone marrow, cerebrospinal fluid (CSF), or lungs (other than cancer that has spread to the lungs from nearby areas). Patients who are infected with the Epstein-Barr virus or whose AIDS-related lymphoma affects the bone marrow have an increased risk of the cancer spreading to the central nervous system (CNS). For treatment, AIDS-related lymphomas are grouped based on where they started in the body, as follows: Peripheral/systemic lymphoma Lymphoma that starts in the lymph system or elsewhere in the body, other than the brain, is called peripheral/systemic lymphoma. It may spread throughout the body, including to the brain or bone marrow. It is often diagnosed in an advanced stage. Primary CNS lymphoma Primary CNS lymphoma starts in the central nervous system (brain and spinal cord). It is linked to the Epstein-Barr virus. Lymphoma that starts somewhere else in the body and spreads to the central nervous system is not primary CNS lymphoma.

### Question: What are the stages of Bile Duct Cancer (Cholangiocarcinoma) ? ### Answer:

Key Points - The results of diagnostic and staging tests are used to find out if cancer cells have spread. - There are three ways that cancer spreads in the body. - Cancer may spread from where it began to other parts of the body. - Stages are used to describe the different types of bile duct cancer. - Intrahepatic bile duct cancer - Perihilar bile duct cancer - Distal extrahepatic bile duct cancer - The following groups are used to plan treatment: - Resectable (localized) bile duct cancer - Unresectable, metastatic, or recurrent bile duct cancer The results of diagnostic and staging tests are used to find out if cancer cells have spread. The process used to find out if cancer has spread to other parts of the body is called staging. For bile duct cancer, the information gathered from tests and procedures is used to plan treatment, including whether the tumor can be removed by surgery. There are three ways that cancer spreads in the body. Cancer can spread through tissue, the lymph system, and the blood: - Tissue. The cancer spreads from where it began by growing into nearby areas. - Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body. - Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body. Cancer may spread from where it began to other parts of the body. When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood. - Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body. - Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body. The metastatic tumor is the same type of cancer as the primary tumor. For example, if bile duct cancer spreads to the liver, the cancer cells in the liver are actually bile duct cancer cells. The disease is metastatic bile duct cancer, not liver cancer. Stages are used to describe the different types of bile duct cancer. Intrahepatic bile duct cancer - Stage 0: Abnormal cells are found in the innermost layer of tissue lining the intrahepatic bile duct. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ. - Stage I: There is one tumor that has spread into the intrahepatic bile duct and it has not spread into any blood vessels. - Stage II: There is one tumor that has spread through the wall of the bile duct and into a blood vessel, or there are multiple tumors that may have spread into a blood vessel. - Stage III: The tumor has spread through the tissue that lines the abdominal wall or has spread to organs or tissues near the liver such as the duodenum, colon, and stomach. - Stage IV: Stage IV is divided into stage IVA and stage IVB. - Stage IVA: The cancer has spread along the outside of the intrahepatic bile ducts or the cancer has spread to nearby lymph nodes. - Stage IVB: The cancer has spread to organs in other parts of the body. Perihilar bile duct cancer - Stage 0: Abnormal cells are found in the innermost layer of tissue lining the perihilar bile duct. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ. - Stage I: Cancer has formed in the innermost layer of the wall of the perihilar bile duct and has spread into the muscle layer or fibrous tissue layer of the wall. - Stage II: Cancer has spread through the wall of the perihilar bile duct to nearby fatty tissue or to the liver. - Stage III: Stage III is divided into stage IIIA and stage IIIB. - Stage IIIA: Cancer has spread to branches on one side of the hepatic artery or of the portal vein. - Stage IIIB: Cancer has spread to nearby lymph nodes. Cancer may have spread into the wall of the perihilar bile duct or through the wall to nearby fatty tissue, the liver, or to branches on one side of the hepatic artery or of the portal vein. - Stage IV: Stage IV is divided into stage IVA and stage IVB. - Stage IVA: Cancer has spread to one or more of the following: - the main part of the portal vein and/or common hepatic artery; - the branches of the portal vein and/or common hepatic artery on both sides; - the right hepatic duct and the left branch of the hepatic artery or of the portal vein; - the left hepatic duct and the right branch of the hepatic artery or of the portal vein. Cancer may have spread to nearby lymph nodes. - Stage IVB: Cancer has spread to lymph nodes in more distant parts of the abdomen, or to organs in other parts of the body. Distal extrahepatic bile duct cancer - Stage 0: Abnormal cells are found in the innermost layer of tissue lining the distal extrahepatic bile duct. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ. - Stage I: Stage I is divided into stage IA and stage IB. - Stage IA: Cancer has formed and is found in the distal extrahepatic bile duct wall only. - Stage IB: Cancer has formed and has spread through the wall of the distal extrahepatic bile duct but has not spread to nearby organs. - Stage II: Stage II is divided into stage IIA and stage IIB. - Stage IIA: Cancer has spread from the distal extrahepatic bile duct to the gallbladder, pancreas, duodenum, or other nearby organs. - Stage IIB: Cancer has spread from the distal extrahepatic bile duct to nearby lymph nodes. Cancer may have spread through the wall of the duct or to nearby organs. - Stage III: Cancer has spread to the large vessels that carry blood to the organs in the abdomen. Cancer may have spread to nearby lymph nodes. - Stage IV: Cancer has spread to organs in distant parts of the body. The following groups are used to plan treatment: Resectable (localized) bile duct cancer The cancer is in an area, such as the lower part of the common bile duct or perihilar area, where it can be removed completely by surgery. Unresectable, metastatic, or recurrent bile duct cancer Unresectable cancer cannot be removed completely by surgery. Most patients with bile duct cancer cannot have their cancer completely removed by surgery. Metastasis is the spread of cancer from the primary site (place where it started) to other places in the body. Metastatic bile duct cancer may have spread to the liver, other parts of the abdominal cavity, or to distant parts of the body. Recurrent bile duct cancer is cancer that has recurred (come back) after it has been treated. The cancer may come back in the bile ducts, liver, or gallbladder. Less often, it may come back in distant parts of the body.

### Question: What causes Overweight and Obesity ? ### Answer:

Lack of Energy Balance A lack of energy balance most often causes overweight and obesity. Energy balance means that your energy IN equals your energy OUT. Energy IN is the amount of energy or calories you get from food and drinks. Energy OUT is the amount of energy your body uses for things like breathing, digesting, and being physically active. To maintain a healthy weight, your energy IN and OUT don't have to balance exactly every day. It's the balance over time that helps you maintain a healthy weight. The same amount of energy IN and energy OUT over time = weight stays the same More energy IN than energy OUT over time = weight gain More energy OUT than energy IN over time = weight loss Overweight and obesity happen over time when you take in more calories than you use. Other Causes An Inactive Lifestyle Many Americans aren't very physically active. One reason for this is that many people spend hours in front of TVs and computers doing work, schoolwork, and leisure activities. In fact, more than 2 hours a day of regular TV viewing time has been linked to overweight and obesity. Other reasons for not being active include: relying on cars instead of walking, fewer physical demands at work or at home because of modern technology and conveniences, and lack of physical education classes in schools. People who are inactive are more likely to gain weight because they don't burn the calories that they take in from food and drinks. An inactive lifestyle also raises your risk for coronary heart disease, high blood pressure, diabetes, colon cancer, and other health problems. Environment Our environment doesn't support healthy lifestyle habits; in fact, it encourages obesity. Some reasons include: Lack of neighborhood sidewalks and safe places for recreation. Not having area parks, trails, sidewalks, and affordable gyms makes it hard for people to be physically active. Work schedules. People often say that they don't have time to be physically active because of long work hours and time spent commuting. Oversized food portions. Americans are exposed to huge food portions in restaurants, fast food places, gas stations, movie theaters, supermarkets, and even at home. Some of these meals and snacks can feed two or more people. Eating large portions means too much energy IN. Over time, this will cause weight gain if it isn't balanced with physical activity. Lack of access to healthy foods. Some people don't live in neighborhoods that have supermarkets that sell healthy foods, such as fresh fruits and vegetables. Or, for some people, these healthy foods are too costly. Food advertising. Americans are surrounded by ads from food companies. Often children are the targets of advertising for high-calorie, high-fat snacks and sugary drinks. The goal of these ads is to sway people to buy these high-calorie foods, and often they do. Genes and Family History Studies of identical twins who have been raised apart show that genes have a strong influence on a person's weight. Overweight and obesity tend to run in families. Your chances of being overweight are greater if one or both of your parents are overweight or obese. Your genes also may affect the amount of fat you store in your body and where on your body you carry the extra fat. Because families also share food and physical activity habits, a link exists between genes and the environment. Children adopt the habits of their parents. A child who has overweight parents who eat high-calorie foods and are inactive will likely become overweight too. However, if the family adopts healthy food and physical activity habits, the child's chance of being overweight or obese is reduced. Health Conditions Some hormone problems may cause overweight and obesity, such as underactive thyroid (hypothyroidism), Cushing's syndrome, and polycystic ovarian syndrome (PCOS). Underactive thyroid is a condition in which the thyroid gland doesn't make enough thyroid hormone. Lack of thyroid hormone will slow down your metabolism and cause weight gain. You'll also feel tired and weak. Cushing's syndrome is a condition in which the body's adrenal glands make too much of the hormone cortisol. Cushing's syndrome also can develop if a person takes high doses of certain medicines, such as prednisone, for long periods. People who have Cushing's syndrome gain weight, have upper-body obesity, a rounded face, fat around the neck, and thin arms and legs. PCOS is a condition that affects about 510 percent of women of childbearing age. Women who have PCOS often are obese, have excess hair growth, and have reproductive problems and other health issues. These problems are caused by high levels of hormones called androgens. Medicines Certain medicines may cause you to gain weight. These medicines include some corticosteroids, antidepressants, and seizure medicines. These medicines can slow the rate at which your body burns calories, increase your appetite, or cause your body to hold on to extra water. All of these factors can lead to weight gain. Emotional Factors Some people eat more than usual when they're bored, angry, or stressed. Over time, overeating will lead to weight gain and may cause overweight or obesity. Smoking Some people gain weight when they stop smoking. One reason is that food often tastes and smells better after quitting smoking. Another reason is because nicotine raises the rate at which your body burns calories, so you burn fewer calories when you stop smoking. However, smoking is a serious health risk, and quitting is more important than possible weight gain. Age As you get older, you tend to lose muscle, especially if you're less active. Muscle loss can slow down the rate at which your body burns calories. If you don't reduce your calorie intake as you get older, you may gain weight. Midlife weight gain in women is mainly due to aging and lifestyle, but menopause also plays a role. Many women gain about 5 pounds during menopause and have more fat around the waist than they did before. Pregnancy During pregnancy, women gain weight to support their babies growth and development. After giving birth, some women find it hard to lose the weight. This may lead to overweight or obesity, especially after a few pregnancies. Lack of Sleep Research shows that lack of sleep increases the risk of obesity. For example, one study of teenagers showed that with each hour of sleep lost, the odds of becoming obese went up. Lack of sleep increases the risk of obesity in other age groups as well. People who sleep fewer hours also seem to prefer eating foods that are higher in calories and carbohydrates, which can lead to overeating, weight gain, and obesity. Sleep helps maintain a healthy balance of the hormones that make you feel hungry (ghrelin) or full (leptin). When you don't get enough sleep, your level of ghrelin goes up and your level of leptin goes down. This makes you feel hungrier than when you're well-rested. Sleep also affects how your body reacts to insulin, the hormone that controls your blood glucose (sugar) level. Lack of sleep results in a higher than normal blood sugar level, which may increase your risk for diabetes. For more information, go to the Health Topics Sleep Deprivation and Deficiency article.

### Question: How to diagnose Fanconi Anemia ? ### Answer:

People who have Fanconi anemia (FA) are born with the disorder. They may or may not show signs or symptoms of it at birth. For this reason, FA isn't always diagnosed when a person is born. In fact, most people who have the disorder are diagnosed between the ages of 2 and 15 years. The tests used to diagnose FA depend on a person's age and symptoms. In all cases, medical and family histories are an important part of diagnosing FA. However, because FA has many of the same signs and symptoms as other diseases, only genetic testing can confirm its diagnosis. Specialists Involved A geneticist is a doctor or scientist who studies how genes work and how diseases and traits are passed from parents to children through genes. Geneticists do genetic testing for FA. They also can provide counseling about how FA is inherited and the types of prenatal (before birth) testing used to diagnose it. An obstetrician may detect birth defects linked to FA before your child is born. An obstetrician is a doctor who specializes in providing care for pregnant women. After your child is born, a pediatrician also can help find out whether your child has FA. A pediatrician is a doctor who specializes in treating children and teens. A hematologist (blood disease specialist) also may help diagnose FA. Family and Medical Histories FA is an inherited disease. Some parents are aware that their family has a medical history of FA, even if they don't have the disease. Other parents, especially if they're FA carriers, may not be aware of a family history of FA. Many parents may not know that FA can be passed from parents to children. Knowing your family medical history can help your doctor diagnose whether you or your child has FA or another condition with similar symptoms. If your doctor thinks that you, your siblings, or your children have FA, he or she may ask you detailed questions about: Any personal or family history of anemia Any surgeries youve had related to the digestive system Any personal or family history of immune disorders Your appetite, eating habits, and any medicines you take If you know your family has a history of FA, or if your answers to your doctor's questions suggest a possible diagnosis of FA, your doctor will recommend further testing. Diagnostic Tests and Procedures The signs and symptoms of FA aren't unique to the disease. They're also linked to many other diseases and conditions, such as aplastic anemia. For this reason, genetic testing is needed to confirm a diagnosis of FA. Genetic tests for FA include the following. Chromosome Breakage Test This is the most common test for FA. It's available only in special laboratories (labs). It shows whether your chromosomes (long chains of genes) break more easily than normal. Skin cells sometimes are used for the test. Usually, though, a small amount of blood is taken from a vein in your arm using a needle. A technician combines some of the blood cells with certain chemicals. If you have FA, the chromosomes in your blood sample break and rearrange when mixed with the test chemicals. This doesn't happen in the cells of people who don't have FA. Cytometric Flow Analysis Cytometric flow analysis, or CFA, is done in a lab. This test examines how chemicals affect your chromosomes as your cells grow and divide. Skin cells are used for this test. A technician mixes the skin cells with chemicals that can cause the chromosomes in the cells to act abnormally. If you have FA, your cells are much more sensitive to these chemicals. The chromosomes in your skin cells will break at a high rate during the test. This doesn't happen in the cells of people who don't have FA. Mutation Screening A mutation is an abnormal change in a gene or genes. Geneticists and other specialists can examine your genes, usually using a sample of your skin cells. With special equipment and lab processes, they can look for gene mutations that are linked to FA. Diagnosing Different Age Groups Before Birth (Prenatal) If your family has a history of FA and you get pregnant, your doctor may want to test you or your fetus for FA. Two tests can be used to diagnose FA in a developing fetus: amniocentesis (AM-ne-o-sen-TE-sis) and chorionic villus (ko-re-ON-ik VIL-us) sampling (CVS). Both tests are done in a doctor's office or hospital. Amniocentesis is done 15 to 18 weeks after a pregnant woman's last period. A doctor uses a needle to remove a small amount of fluid from the sac around the fetus. A technician tests chromosomes (chains of genes) from the fluid sample to see whether they have faulty genes associated with FA. CVS is done 10 to 12 weeks after a pregnant woman's last period. A doctor inserts a thin tube through the vagina and cervix to the placenta (the temporary organ that connects the fetus to the mother). The doctor removes a tissue sample from the placenta using gentle suction. The tissue sample is sent to a lab to be tested for genetic defects associated with FA. At Birth Three out of four people who inherit FA are born with birth defects. If your baby is born with certain birth defects, your doctor may recommend genetic testing to confirm a diagnosis of FA. For more information about these defects, go to What Are the Signs and Symptoms of Fanconi Anemia? Childhood and Later Some people who have FA are not born with birth defects. Doctors may not diagnose them with the disorder until signs of bone marrow failure or cancer occur. This usually happens within the first 10 years of life. Signs of bone marrow failure most often begin between the ages of 3 and 12 years, with 7 to 8 years as the most common ages. However, 10 percent of children who have FA aren't diagnosed until after 16 years of age. If your bone marrow is failing, you may have signs of aplastic anemia. FA is one type of aplastic anemia. In aplastic anemia, your bone marrow stops making or doesn't make enough of all three types of blood cells: red blood cells, white blood cells, and platelets. Aplastic anemia can be inherited or acquired after birth through exposure to chemicals, radiation, or medicines. Doctors diagnose aplastic anemia using: Family and medical histories and a physical exam. A complete blood count (CBC) to check the number, size, and condition of your red blood cells. The CBC also checks numbers of white blood cells and platelets. A reticulocyte (re-TIK-u-lo-site) count. This test counts the number of new red blood cells in your blood to see whether your bone marrow is making red blood cells at the proper rate. Bone marrow tests. For a bone marrow aspiration, a small amount of liquid bone marrow is removed and tested to see whether it's making enough blood cells. For a bone marrow biopsy, a small amount of bone marrow tissue is removed and tested to see whether it's making enough blood cells. If you or your child is diagnosed with aplastic anemia, your doctor will want to find the cause. If your doctor suspects you have FA, he or she may recommend genetic testing.
