Most common cancer types can be treated with radiation therapy in some way. The precise treatment intent will depend on the tumor type, location, and stage, as well as the general health of the patient. Total body irradiation (TBI) is a radiation therapy technique used to prepare the body to receive a bone marrow transplant. Brachytherapy, in which a radiation source is placed inside or next to the area requiring treatment, is another form of radiation therapy that minimizes exposure of healthy tissue during procedures to treat cancers of the breast, prostate and other organs.
