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. Radiation is given in a series of treatments to allow healthy cells to recover and to make radiation more effective. The number of treatments is based on details about the cancer, such as the size and location of the tumor. Most of the time, radiation is given as an outpatient treatment. This means that you will have treatment at a clinic or radiation therapy center and will not stay overnight in the hospital.
