What is Radiation Therapy?
Radiation therapy is one of the most common treatments for cancer. It uses special equipment to aim high doses of radiation at cancer cells. This damages the cancer cells and causes them to die.
Radiation therapy can be a highly effective method of treating different cancer types including cancer of the bladder, brain, head and neck, lung, breast, prostate, skin, rectum, stomach, testicles, cervix and uterus, among others. It may also be used to combat lymphoma and sarcoma. Radiation therapy can be given alone or used with other treatments, such as surgery or chemotherapy.
Unlike chemotherapy, which exposes the whole body to cancer-fighting drugs, radiation therapy is usually a local treatment. It targets only the part of the body being treated. The goal of radiation treatment is to damage as many cancer cells as possible, with little harm to nearby healthy tissue.
One of the reasons referring physicians recommend St. Teresa Comprehensive Cancer Center is because they know we offer the latest, most sophisticated radiation therapy planning and delivery systems. This ensures that you and your Radiation Oncologist can choose the best treatment option given your type of cancer, its stage and location. Why is this so important? The more precisely we can target your tumor site, the lower the risk of side effects and the chance of a recurrence.
When is radiation therapy used?
Radiation therapy can be used alone or as part of a cancer treatment plan that may also include surgery, chemotherapy, hormonal or biological therapies. It may be used in an effort to eliminate the cancer, or to treat unpleasant symptoms the cancer is causing; such as pain or bleeding.
Depending on the type of radiation therapy technology used, patients may receive treatment in a single session or through a series of visits over a period that can last anywhere from one to eight weeks.
