Radiation therapy is defined as the use of hight energy X-rays or particles to treat disease. The goal of radiation therapy is to kill the cancer cells while sparing the normal surrounding tissue. Radiation therapy may be used alone or combined with other treatments such as chemotherapy and/or surgery. The MMC Radiation Therapy Department consists of three separate Treatment Centers: Coastal Cancer Treatment Center in Bath, Maine, the Scarborough Radiation Therapy Center in Scarborough, Maine and the Southern Maine Radiation Therapy Center at the main hospital campus in Portland, Maine. This multi-center approach allows patients to remain closer to home while undergoing their course of radiation treatment.
