Genetic Disorders Directory
Genetic disorders are diseases that are caused by abnormal DNA or mutations. These abnomalities can be small changes to a single gene or be much more complex and affect a chromosome or an entire group of chromosomes. Genetic disorders cause a long list of diseases from cystic fibrosis to being more suseptable to various types of cancers. Find out more about various genetic disorders with articles, news and more.
Nasopharyngeal Cancer Treatment (PDQ®): Treatment - Patient Information [NCI]-Treatment Options for Recurrent Nasopharyngeal Cancer
Treatment of recurrent nasopharyngeal cancer may include the following:Intensity-modulated radiation therapy, stereotactic radiation therapy, or internal radiation therapy.Surgery.Chemotherapy.A clinical trial of chemotherapy.A clinical trial of stereotactic radiation therapy.Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with recurrent nasopharyngeal 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. General information about clinical trials is available from the NCI Web site.

Nasopharyngeal Cancer Treatment (PDQ®): Treatment - Patient Information [NCI]-Treatment Option Overview
There are different types of treatment for patients with nasopharyngeal cancer. Different types of treatment are available for patients with nasopharyngeal 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.Three types of standard treatment are used: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
Nasopharyngeal Cancer Treatment (PDQ®): Treatment - Patient Information [NCI]-Stages of Nasopharyngeal Cancer
After nasopharyngeal cancer has been diagnosed, tests are done to find out if cancer cells have spread within the nasopharynx or to other parts of the body. The process used to find out whether cancer has spread within the nasopharynx 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 nasopharyngeal cancer are often also used to stage the disease. (See the General Information section.)There are three ways that cancer spreads in the body.The three ways that cancer spreads in the body are:Through tissue. Cancer invades the surrounding normal tissue.Through the lymph system. Cancer invades the lymph system and travels through the lymph vessels to other places in the body.Through the blood. Cancer invades the veins and capillaries and travels through the blood to other places in the body.When cancer
