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 for brain tumors is generally recommended because of the tumorâs proximity to delicate and vitally important tissues and structures. Whatâs more, primary brain cancer tumors generally start â and stay â in the brain, making them even more eligible for proton therapy.
