Overview and Indications
Radiation therapy is used to fight many types of cancer. Sometimes, radiation is the only treatment needed. It may also be used to shrink a tumor as much as possible before surgery, help prevent the cancer from coming back after surgery or chemotherapy, relieve symptoms caused by a tumor and/or treat cancers that cannot be removed with surgery. Radiation therapy is a cancer treatment that uses high-energy radiation to kill cancer cells. Radiation may be delivered by a machine or from radioactive material placed in the body (brachytherapy).
Radiation therapy offered at the USC Norris Comprehensive Cancer Center includes 3-D conformal radiotherapy (3-D CRT), Intensity Modulated Radiation Therapy (IMRT), Image Guided Radiation Therapy (IGRT), Gamma Knife® Stereotactic Radiosurgery (SRS) to the brain, clinical brachytherapy utilizing high dose-rate (HDR), episcleral eye plaque brachytherapy, RapidArc or VMAT treatment delivery and Stereotactic Body Radiation Therapy (SBRT) to multiple disease sites.
