Proton therapy is a type of radiation treatment that uses protons, which are positively charged particles, to target and destroy cancer cells. Unlike traditional X-ray radiation, which can affect surrounding healthy tissue, proton therapy delivers precise doses of radiation directly to the tumor, minimizing damage to nearby organs. This treatment is particularly effective for certain types of cancer, such as pediatric cancers and tumors located near critical structures, like the brain or spine. Proton therapy is often chosen for its ability to reduce side effects and improve the quality of life for patients undergoing cancer treatment.
