Radiation therapy (also called radiotherapy) uses high-energy radiation from x-rays and other sources to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external radiation therapy) or from materials that produce radiation (radioisotopes) that are placed inside the body in the area where the cancer cells are found (internal radiation therapy, implant radiation, or brachytherapy). ...
