About Your Cancer
Radiation therapy (also called therapeutic radiology or radiation oncology) uses special kinds of energy waves or particles to fight cancer. Like surgery, radiation therapy is used in several ways depending on the type and location of the cancer. Certain levels of radiation work to destroy cancer cells or prevent cells from growing or reproducing. This treatment may provide a cure for cancer, control the disease, or help relieve its symptoms. Most radiation treatments won't make you radioactive. Talk to your doctor about any precautions you should take when getting radiation therapy.
