What is radiation therapy?

Radiation therapy, sometimes called radiotherapy, uses various forms of high energy radiation, like X-rays, to safely and effectively destroy cancer, among other diseases. Radiation has been used against cancer for over 100 years. More than half of all cancer patients undergo radiation therapy. For some, radiation therapy is the only cancer treatment needed. In many cases, the cancer must be treated with more than one type of treatment. For example, a surgeon might remove a tumor from a patient, who will then require radiation therapy to destroy any remaining cancer cells. Patients also may receive chemotherapy from a medical oncologist to destroy cancer cells that have traveled to other parts of the body, and thus this is called systemic therapy. Like surgery, radiation therapy is considered a “local” therapy, meaning it treats a specific, localized area of the body.

Before patients receive radiation therapy, the radiation oncologist, physicist and dosimetrists work together using sophisticated computer software to calculate the best treatment for each patient’s body and tumor. This treatment planning ensures that the tumor site receives the maximum amount of radiation while minimizing exposure to healthy tissue and organs.
