Question:  What are the symptoms of Heart Attack ?
Answer: Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes or goes away and comes back. The discomfort can feel like uncomfortable pressure, squeezing, fullness, or pain. It can include pain or numbness in one or both arms, the back, neck, jaw, or stomach. Heart attack pain can sometimes feel like indigestion or heartburn. Shortness of breath often happens along with, or before chest discomfort. Other symptoms may include breaking out in a cold sweat, having nausea and vomiting, or feeling light-headed or dizzy. Symptoms vary, and some people have no symptoms. Know the symptoms of a heart attack so you can act fast to get treatment.
Question:  What are the symptoms of Heart Attack ?
Answer: No. Most heart attack patients do not have all of the symptoms. The important thing to remember is that if you have any of the symptoms and they grow more intense, and last more than 5 minutes, you should call 9-1-1 immediately.
Question:  How many people are affected by Heart Attack ?
Answer: Very common. Each year, more than 1 million people in the U.S. have a heart attack and about half of them die. About one-half of those who die do so within 1 hour of the start of symptoms and before reaching the hospital.
Question:  Who is at risk for Heart Attack? ?
Answer: Certain factors increase the risk of developing coronary heart disease and having a heart attack. These risk factors include some things you cannot change. You are at greater risk if you -  are a man over age 45 or a woman over age 55.  -  have a family history of early heart disease -- heart disease in a father or brother before age 55 or in a mother or sister before age 65.   - have a personal history of angina or previous heart attack.   -  have had a heart procedure, such as angioplasty or heart bypass. are a man over age 45 or a woman over age 55. have a family history of early heart disease -- heart disease in a father or brother before age 55 or in a mother or sister before age 65. have a personal history of angina or previous heart attack. have had a heart procedure, such as angioplasty or heart bypass. Importantly, there are many risk factors for heart attack that you CAN change, including -  smoking  - being obese or overweight  - being physically inactive   -  having high blood pressure, high blood cholesterol or diabetes. smoking being obese or overweight being physically inactive having high blood pressure, high blood cholesterol or diabetes.
Question:  Who is at risk for Heart Attack? ?
Answer: You can lower your risk of having a heart attack, even if you have already had a heart attack or have been told that your chances of having a heart attack are high. To prevent a heart attack, you will need to make lifestyle changes. You may also need to get treatment for conditions that raise your risk. Lifestyle changes you can make to lower your risk for heart attack include the following: - If you smoke, quit.  - Maintain a healthy weight. Lose weight gradually if you are overweight or obese. If you smoke, quit. Maintain a healthy weight. Lose weight gradually if you are overweight or obese. - Follow a heart healthy diet  -- such as one low in salt, saturated fat and trans fat, and calories -- to prevent or reduce high blood pressure and high blood cholesterol and maintain a healthy weight.  - Be as physically active as you can.

Question:  How to diagnose Heart Attack ?
Answer: Several tests are used to diagnose a heart attack. - An electrocardiogram, also called an EKG, measures the rate and regularity of your heartbeat.  - Blood tests identify and measure markers in the blood that can show how much damage was done to your heart. These tests are often repeated at specific time periods to check for changes.  - A nuclear heart scan uses radioactive tracers to show damage to heart chambers and major blood vessels.  - Cardiac catheterization involves passing a thin flexible tube through an artery in your groin or arm to look at your coronary arteries. It allows your doctor to examine the blood flow in your heart's chambers.  - Cardiac angiography is usually performed along with cardiac catheterization, using a dye injected through the cardiac catheter. The dye allows the doctor to see where there may be blockages in the coronary arteries. An electrocardiogram, also called an EKG, measures the rate and regularity of your heartbeat.

Question:  What are the treatments for Heart Attack ?
Answer: If you are having a heart attack, doctors will work quickly to restore blood flow to the heart and continuously monitor vital signs to detect and treat complications. Restoring blood flow to the heart can prevent or limit damage to the heart muscle and help prevent another heart attack. Doctors may use clot-busting drugs called thrombolytics and procedures, such as angioplasty. Long-term treatment after a heart attack may include cardiac rehabilitation, checkups and tests, lifestyle changes, and medications.
Question:  What is (are) Heart Attack ?
Answer: Angina is a recurring pain or discomfort in the chest that happens when some part of the heart does not receive enough blood. An episode of angina is not a heart attack. However, people with angina may have a hard time telling the difference between angina and heart attack symptoms. Angina is chest pain or discomfort that occurs when your heart muscle does not get enough blood. Angina may feel like pressure or a squeezing pain in your chest. The pain may also occur in your shoulders, arms, neck, jaw, or back. It may also feel like indigestion. It is usually relieved within a few minutes by resting or by taking prescribed angina medicine.
Question:  What are the treatments for Heart Attack ?
Answer: There are many medicines that are used to treat a heart attack. - Clot-busters or thrombolytic drugs dissolve blood clots that are blocking blood flow to the heart.  - Beta blockers decrease the workload on your heart by slowing your heart rate.  - Angiotensin-converting enzyme (ACE) inhibitors lower your blood pressure and reduce the strain on your heart.  - Nitrates, such as nitroglycerin  relax blood vessels and relieve chest pain.  - Anticoagulants thin the blood and prevent clots from forming in your arteries.  - Antiplatelet medications, such as aspirin and clopidogrel, stop platelets from clumping together to form clots. These medications are given to people who have had a heart attack, have angina, or have had angioplasty.

Question:  What is (are) Colorectal Cancer ?
Answer: How Tumors Form The body is made up of many types of cells. Normally, cells grow, divide, and produce more cells as needed to keep the body healthy and functioning properly. Sometimes, however, the process goes wrong -- cells become abnormal and form more cells in an uncontrolled way. These extra cells form a mass of tissue, called a growth or tumor. Tumors can be benign, which means not cancerous, or malignant, which means cancerous. How Colorectal Cancer Develops Cancer of the colon or rectum is called colorectal cancer. The colon and the rectum are part of the large intestine, which is part of the digestive system. Colorectal cancer occurs when tumors form in the lining of the large intestine, also called the large bowel. Colorectal cancer accounts for almost ten percent of all cancer deaths in the United States. The risk of developing colorectal cancer rises after age 50. It is common in both men and women. Colorectal Cancer Can Spread Sometimes, cancer cells break away from the malignant tumor and enter the bloodstream or the lymphatic system where they travel to other organs in the body. Among other things, the lymphatic system transports white blood cells that fight infection. When cancer travels or spreads from its original location in the colon to another part of the body such as the liver, it is called metastatic colorectal cancer and not liver cancer. When colorectal cancer does spread, it tends to spread to the liver or lungs. Cure Rate for Early Detection Today there are more ways than ever to treat colorectal cancer. As with almost all cancers, the earlier it is found, the more likely that the treatment will be successful. If colon cancer is detected in its early stages, it is up to 90 percent curable.
Question:  Who is at risk for Colorectal Cancer? ?
Answer: Scientists don't know exactly what causes colorectal cancer, but they have been able to identify some risk factors for the disease. A risk factor is anything that increases your chances of getting a disease. Studies show that the following risk factors may increase a person's chances of developing colorectal cancer: age, polyps, personal history, family history, and ulcerative colitis. Age Colorectal cancer is more likely to occur as people get older. It is more common in people over the age of 50, but younger people can get it, too. In rare cases, it can occur in adolescence. Polyps Polyps are benign, or non-cancerous, growths on the inner wall of the colon and rectum. They are fairly common in people over age 50. Some types of polyps increase a person's risk of developing colorectal cancer. Not all polyps become cancerous, but nearly all colon cancers start as polyps. Diet The link between diet and colorectal cancer is not firmly established. There is evidence that smoking cigarettes and drinking 3 or more alcoholic beverages daily may be associated with an increased risk of colorectal cancer. Personal History Research shows that women with a history of cancer of the ovary, uterus, or breast have a somewhat increased chance of developing colorectal cancer. Also, a person who has already had colorectal cancer may develop this disease a second time. Family History The parents, siblings, and children of a person who has had colorectal cancer are somewhat more likely to develop this type of cancer themselves. This is especially true if the relative had the cancer at a young age. If many family members have had colorectal cancer, the chances increase even more. Ulcerative colitis Ulcerative colitis is a condition in which there is a chronic break in the lining of the colon. Having this condition increases a person's chance of developing colorectal cancer. Genetic Mutations Researchers have identified genetic mutations, or abnormalities, that may be linked to the development of colon cancer. They are working to unravel the exact ways these genetic changes occur. Recent results from The Cancer Genome Atlas study of colorectal cancer point to several genes (BRAF and EGRF among others) that may increase risk. If You Have Risk Factors If you have one or more of these risk factors, it doesn't mean you will get colorectal cancer. It just increases the chances. You may wish to talk to your doctor about these risk factors. He or she may be able to suggest ways you can reduce your chances of developing colorectal cancer and plan an appropriate schedule for checkups.
Question:  What are the treatments for Colorectal Cancer ?
Answer: There are several treatment options for colorectal cancer, although most treatments begin with surgical removal of either the cancerous polyp or section of the colon. The choice of treatment depends on your age and general health, the stage of cancer, whether or not it has spread beyond the colon, and other factors. If tests show that you have cancer, you should talk with your doctor and make treatment decisions as soon as possible. Studies show that early treatment leads to better outcomes. Working With a Team of Specialists A team of specialists often treats people with cancer. The team will keep the primary doctor informed about the patient's progress. The team may include a medical oncologist who is a specialist in cancer treatment, a surgeon, a radiation oncologist who is a specialist in radiation therapy, and others. Before starting treatment, you may want another doctor to review the diagnosis and treatment plan. Some insurance companies require a second opinion. Others may pay for a second opinion if you request it. Clinical Trials for Colorectal Cancer Some colorectal cancer patients take part in studies of new treatments. These studies, called clinical trials, are designed to find out whether a new treatment is safe and effective. Often, clinical trials compare a new treatment with a standard one so that doctors can learn which is more effective. People with colorectal cancer who are interested in taking part in a clinical trial should talk with their doctor. The U.S. National Institutes of Health, through its National Library of Medicine and other Institutes, maintains a database of clinical trials at ClinicalTrials.gov.

Question:  What are the symptoms of Colorectal Cancer ?
Answer: Possible signs of colorectal cancer include: - a change in the frequency of bowel movements   - diarrhea, constipation, or feeling that the bowel does not empty completely   - either bright red or very dark blood in the stool a change in the frequency of bowel movements diarrhea, constipation, or feeling that the bowel does not empty completely either bright red or very dark blood in the stool - stools that are narrower than usual  - general abdominal discomfort such as frequent gas pains, bloating, fullness, and/or cramps   - weight loss with no known reason  - constant tiredness  - vomiting stools that are narrower than usual general abdominal discomfort such as frequent gas pains, bloating, fullness, and/or cramps weight loss with no known reason constant tiredness vomiting
Question:  What is (are) Colorectal Cancer ?
Answer: Here are some of the tools used to detect colorectal cancer. - A fecal occult blood test, or FOBT, is a test used to check for hidden blood in the stool. Sometimes cancers or polyps can bleed, and FOBT can detect small amounts of bleeding. Newer, genetically-based stool tests are proving to be more accurate than older tests.

Question:  What is (are) Colorectal Cancer ?
Answer: Yes. In July 2008, the U.S. Preventive Services Task Force made its strongest ever recommendation for colorectal cancer screening: it suggested that all adults between ages 50 and 75 get screened, or tested, for the disease. The task force noted that various screening tests are available, making it possible for patients and their clinicians to decide which test is best for each person.
Question:  What is (are) Colorectal Cancer ?
Answer: The three standard treatments for colon cancer are surgery, chemotherapy, and radiation. Surgery, however, is the most common first step in the treatment for all stages of colon cancer. Surgery is an operation to remove the cancer. A doctor may remove the cancer using several types of surgery. For rectal cancer, radiation treatment also is an option.
Question:  What is (are) Colorectal Cancer ?
Answer: Several types of surgery are available for someone with colorectal cancer. If the cancer is found at a very early stage, the doctor may remove it without cutting through the abdominal wall. Instead, the doctor may put a tube up the rectum into the colon and cut the cancer out. This is called a local excision. If the cancer is found in a polyp, which is a small bulging piece of tissue, the operation is called a polypectomy. If the cancer is larger, the surgeon will remove the cancer and a small amount of healthy tissue around it. This is called a colectomy. The surgeon may then sew the healthy parts of the colon together. Usually, the surgeon will also remove lymph nodes near the colon and examine them under a microscope to see whether they contain cancer. If the doctor is not able to sew the two ends of the colon back together, an opening called a stoma is made on the abdomen for waste to pass out of the body before it reaches the rectum. This procedure is called a colostomy. Sometimes the colostomy is needed only until the lower colon has healed, and then it can be reversed. But if the doctor needs to remove the entire lower colon, the colostomy may be permanent.
