Proton therapy is an advanced type of radiation treatment that uses a beam of protons to deliver radiation directly to the tumor, destroying cancer cells while sparing healthy tissues. Protons enter the body with a low radiation dose, stop at the tumor, match its shape and volume or depth, and deposit the bulk of their cancer-fighting energy right at the tumor.
Proton therapy, also called Proton beam therapy, is the most advanced radiation therapy available today-it destroys cancer cells but does not attack surrounding healthy tissue nearly as much as traditional radiation therapy does.he National Health Service 1 in the UK says that proton therapy is better with some rare cancers where the tumors are located at the base of the skull or spine. With traditional radiation therapy, such tumors cannot be targeted because of the risk of damage to vital surrounding tissue (nerves).
