How to diagnose Ovarian Low Malignant Potential Tumors ? 

Tests that examine the ovaries are used to detect (find), diagnose, and stage ovarian low malignant potential tumor. The following tests and procedures may be used:         -   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.    -   Pelvic exam : An exam of the vagina, cervix, uterus, fallopian tubes, ovaries, and rectum. A speculum is inserted into the vagina and the doctor or nurse looks at the vagina and cervix for signs of disease. A Pap test of the cervix is usually done. The doctor or nurse also inserts one or two lubricated, gloved fingers of one hand into the vagina and places the other hand over the lower abdomen to feel the size, shape, and position of the uterus and ovaries. The doctor or nurse also inserts a lubricated, gloved finger into the rectum to feel for lumps or abnormal areas.    -   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. The picture can be printed to be looked at later.Other patients may have a transvaginal ultrasound.     -   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.     -   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.    -   Biopsy : The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. The tissue is usually removed during surgery to remove the tumor.
What is the outlook for Ovarian Low Malignant Potential Tumors ? 

Certain factors affect prognosis (chance of recovery) and treatment options.The prognosis (chance of recovery) and treatment options depend on the following:          - The stage of the disease (whether it affects part of the ovary, involves the whole ovary, or has spread to other places in the body).    - What type of cells make up the tumor.    - The size of the tumor.    - The patients general health.         Patients with ovarian low malignant potential tumors have a good prognosis, especially when the tumor is found early.
what research (or clinical trials) is being done for Ovarian Low Malignant Potential Tumors ? 

New types of treatment are being tested in clinical trials.
                    Information about clinical trials is available from the NCI Web site.
                
                
                    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 medical research process. Clinical trials are done to find out if new treatments are safe and effective or better than the standard treatment.   Many of today's standard treatments for disease 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 diseases 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 treatment.
                    Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose disease has not gotten better. There are also clinical trials that test new ways to stop a disease from recurring (coming back) or reduce the side effects of 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 clinical trials database.

                    - Osteosarcoma and malignant fibrous histiocytoma (MFH) of the bone are diseases in which malignant (cancer) cells form in bone.    - Having past treatment with radiation can increase the risk of osteosarcoma.    - Signs and symptoms of osteosarcoma and MFH include swelling over a bone or a bony part of the body and joint pain.     - Imaging tests are used to detect (find) osteosarcoma and MFH.    - A biopsy is done to diagnose osteosarcoma.    - Certain factors affect prognosis (chance of recovery) and treatment options.
                
                
                    Osteosarcoma and malignant fibrous histiocytoma (MFH) of the bone are diseases in which malignant (cancer) cells form in bone.
                    Osteosarcoma usually starts in osteoblasts, which are a type of bone cell that becomes new bone tissue. Osteosarcoma is most common in adolescents. It commonly forms in the ends of the long bones of the body, which include bones of the arms and legs. In children and adolescents, it often forms in the bones near the knee. Rarely, osteosarcoma may be found in soft tissue or organs in the chest or abdomen.   Osteosarcoma is the most common type of bone cancer. Malignant fibrous histiocytoma (MFH) of bone is a rare tumor of the bone. It is treated like osteosarcoma.     Ewing sarcoma is another kind of bone cancer, but it is not covered in this summary. See the PDQ summary about Ewing Sarcoma Treatment for more information.
Who is at risk for Osteosarcoma and Malignant Fibrous Histiocytoma of Bone? ? 

Having past treatment with radiation can increase the risk of osteosarcoma. Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesnt mean that you will not get cancer. Talk with your child's doctor if you think your child may be at risk. Risk factors for osteosarcoma include the following:         - Past treatment with radiation therapy.    - Past treatment with anticancer drugs called alkylating agents.    - Having a certain change in the retinoblastoma gene.    - Having certain conditions, such as the following:               -  Bloom syndrome.      -  Diamond-Blackfan anemia.      -  Li-Fraumeni syndrome.      -  Paget disease.      -  Hereditary retinoblastoma.      -  Rothmund-Thomson syndrome.      -  Werner syndrome.
What are the symptoms of Osteosarcoma and Malignant Fibrous Histiocytoma of Bone ? 

Signs and symptoms of osteosarcoma and MFH include swelling over a bone or a bony part of the body and joint pain. These and other signs and symptoms may be caused by osteosarcoma or MFH or by other conditions. Check with a doctor if your child has any of the following:         - Swelling over a bone or bony part of the body.    - Pain in a bone or joint.    - A bone that breaks for no known reason.
How to diagnose Osteosarcoma and Malignant Fibrous Histiocytoma of Bone ? 

Imaging tests are used to detect (find) osteosarcoma and MFH.
	                        Imaging tests are done before the biopsy. The following tests and procedures may be used:         -   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.    -   X-ray : An x-ray of the organs and bones inside the body. 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.     -   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.    -   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).
	                    
	                    
	                    	A biopsy is done to diagnose osteosarcoma.
	                   		Cells and tissues are removed during a biopsy so they can be viewed under a microscope by a pathologist to check for signs of cancer. It is important that the biopsy be done by a surgeon who is an expert in treating cancer of the bone. It is best if that surgeon is also the one who removes the tumor. The biopsy and the surgery to remove the tumor are planned together. The way the biopsy is done affects which type of surgery can be done later.    The type of biopsy that is done will be based on the size of the tumor and where it is in the body. There are two types of biopsy that may be used:         -   Core biopsy : The removal of tissue using a wide needle.    -   Incisional biopsy : The removal of part of a lump or a sample of tissue that doesn't look normal.         The following test may be done on the tissue that is removed:          -   Light and electron microscopy : A laboratory test in which cells in a sample of tissue are viewed under regular and high-powered microscopes to look for certain changes in the cells.
What is the outlook for Osteosarcoma and Malignant Fibrous Histiocytoma of Bone ? 

Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) is affected by certain factors before and after treatment.    The prognosis of untreated osteosarcoma and MFH depends on the following:         - Where the tumor is in the body and whether tumors formed in more than one bone.    - The size of the tumor.    - Whether the cancer has spread to other parts of the body and where it has spread.    - The type of tumor (based on how the cancer cells look under a microscope).    - The patient's age and weight at diagnosis.    - Whether the tumor has caused a break in the bone.     - Whether the patient has certain genetic diseases.        After osteosarcoma or MFH is treated, prognosis also depends on the following:         - How much of the cancer was killed by chemotherapy.    - How much of the tumor was taken out by surgery.    - Whether chemotherapy is delayed for more than 3 weeks after surgery takes place.    - Whether the cancer has recurred (come back) within 2 years of diagnosis.        Treatment options for osteosarcoma and MFH depend on the following:         - Where the tumor is in the body.    - The size of the tumor.    - The stage of the cancer.    - Whether the bones are still growing.    - The patient's age and general health.    - The desire of the patient and family for the patient to be able to participate in activities such as sports or have a certain appearance.    - Whether the cancer is newly diagnosed or has recurred after treatment.
Who is at risk for Adult Acute Myeloid Leukemia? ? 

Smoking, previous chemotherapy treatment, and exposure to radiation may affect the risk of adult AML. Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesnt mean that you will not get cancer. Talk with your doctor if you think you may be at risk. Possible risk factors for AML include the following:         - Being male.    - Smoking, especially after age 60.    - Having had treatment with chemotherapy or radiation therapy in the past.    - Having had treatment for childhood acute lymphoblastic leukemia (ALL) in the past.    - Being exposed to radiation from an atomic bomb or to the chemical benzene.    - Having a history of a blood disorder such as myelodysplastic syndrome.
What are the symptoms of Adult Acute Myeloid Leukemia ? 

Signs and symptoms of adult AML include fever, feeling tired, and easy bruising or bleeding. The early signs and symptoms of AML may be like those caused by the flu or other common diseases. Check with your doctor if you have any of the following:         -  Fever.    - Shortness of breath.    - Easy bruising or bleeding.    -  Petechiae (flat, pinpoint spots under the skin caused by bleeding).    - Weakness or feeling tired.    - Weight loss or loss of appetite.
How to diagnose Adult Acute Myeloid Leukemia ? 

Tests that examine the blood and bone marrow are used to detect (find) and diagnose adult AML. The following tests and procedures may be used:         -   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.     -   Complete blood count (CBC): A procedure in which a sample of blood is drawn and checked for the following:                - The number of red blood cells, white blood cells, and platelets.      - The amount of hemoglobin (the protein that carries oxygen) in the red blood cells.      - The portion of the sample made up of red blood cells.             -   Peripheral blood smear : A procedure in which a sample of blood is checked for blast cells, the number and kinds of white blood cells, the number of platelets, and changes in the shape of blood cells.     -   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.     -   Cytogenetic analysis : A laboratory test in which the cells in a sample of blood or bone marrow are viewed under a microscope to look for certain changes in the chromosomes. Other tests, such as fluorescence in situ hybridization (FISH), may also be done to look for certain changes in the chromosomes.    -   Immunophenotyping : A process used to identify cells, based on the types of antigens or markers on the surface of the cell. This process is used to diagnose the subtype of AML by comparing the cancer cells to normal cells of the immune system. For example, a cytochemistry study may test the cells in a sample of tissue using chemicals (dyes) to look for certain changes in the sample. A chemical may cause a color change in one type of leukemia cell but not in another type of leukemia cell.    -   Reverse transcriptionpolymerase chain reaction test (RTPCR): A laboratory test in which cells in a sample of tissue are studied using chemicals to look for certain changes in the structure or function of genes. This test is used to diagnose certain types of AML including acute promyelocytic leukemia (APL).
What is the outlook for Adult Acute Myeloid Leukemia ? 

Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options depend on:         - The age of the patient.    - The subtype of AML.    - Whether the patient received chemotherapy in the past to treat a different cancer.    - Whether there is a history of a blood disorder such as myelodysplastic syndrome.    - Whether the cancer has spread to the central nervous system.    - Whether the cancer has been treated before or recurred (come back).         It is important that acute leukemia be treated right away.
What are the stages of Adult Acute Myeloid Leukemia ? 

Key Points
                    - Once adult acute myeloid leukemia (AML) has been diagnosed, tests are done to find out if the cancer has spread to other parts of the body.     - There is no standard staging system for adult AML.
                
                
                    Once adult acute myeloid leukemia (AML) has been diagnosed, tests are done to find out if the cancer has spread to other parts of the body.
                    The extent or spread of cancer is usually described as stages. In adult acute myeloid leukemia (AML), the subtype of AML and whether the leukemia has spread outside the blood and bone marrow are used instead of the stage to plan treatment. The following tests and procedures may be used to determine if the leukemia has spread:         -   Lumbar puncture : A procedure used to collect a sample of 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 leukemia cells have spread to the brain and spinal cord. This procedure is also called an LP or spinal tap.    -   CT scan (CAT scan): A procedure that makes a series of detailed pictures of the abdomen, 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.
                
                
                    There is no standard staging system for adult AML.
                    The disease is described as untreated, in remission, or recurrent.    Untreated adult AML    In untreated adult AML, the disease is newly diagnosed. It has not been treated except to relieve signs and symptoms such as fever, bleeding, or pain, and the following are true:         - The complete blood count is abnormal.    - At least 20% of the cells in the bone marrow are blasts (leukemia cells).    - There are signs or symptoms of leukemia.         Adult AML in remission    In adult AML in remission, the disease has been treated and the following are true:         - The complete blood count is normal.    - Less than 5% of the cells in the bone marrow are blasts (leukemia cells).    - There are no signs or symptoms of leukemia in the brain and spinal cord or elsewhere in the body.         Recurrent Adult AML     Recurrent AML is cancer that has recurred (come back) after it has been treated. The AML may come back in the blood or bone marrow.
what research (or clinical trials) is being done for Adult Acute Myeloid Leukemia ? 

New types of treatment are being tested in clinical trials.
				                    This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website.     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 one type of targeted therapy being studied in the treatment of adult AML.    Monoclonal antibody therapy is a cancer treatment that 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.

what research (or clinical trials) is being done for Oral Cavity and Oropharyngeal 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 certain types of cancer. Some cancer prevention trials are done with healthy people who have not had cancer but who have an increased risk for cancer. Other prevention trials are done 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 oral cavity cancer and oropharyngeal cancer are being studied in clinical trials.
