How many protons strike the tumor each second
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. Web28 jan. 2024 · Proton beam therapy is usually used for localized tumors (stage I, II, or III) and is used infrequently for stage 4 tumors (tumors that have spread to other regions of the body). It may be used alone or combined with other treatments such as surgery, chemotherapy, immunotherapy, or traditional radiation therapy.

WebProton therapy is an advanced form of radiation therapy using a beam of highenergy protons rather - than conventional X-rays to irradiate the tumor. This type of treatment can target a higher dose of radiation to the tumor while avoiding healthy surrounding tissue, thus significantly reducing the risk of secondary radio-induced damage.
