WebProton beam radiation therapy focuses beams of protons instead of photons (x-rays) on the cancer. Unlike photons, which go through the body and expose tissues to radiation both before and after they hit the tumor, protons only travel a certain distance, so the tissues behind the tumor are exposed to very little radiation. WebThe number of treatment sessions depends on the type and stage of the cancer. Sometimes, doctors deliver proton therapy in 1 to 5 proton beam treatments. They generally use larger daily radiation doses for a fewer number of treatments. This is typically called stereotactic body radiotherapy.
