Proton therapy is an advanced form of particle therapy that uses a beam of protons to treat cancer. It more precisely targets radiation dosage to the tumor compared to other radiotherapy. Proton accelerators produce protons with energies between 70-250 MeV that cause DNA damage only in the targeted cells, sparing nearby tissue. This allows protons to deliver maximum dose to just the tumor site via the Bragg peak effect, with very few protons penetrating beyond the target depth. Proton therapy has advantages over x-ray therapy in being more precise with avoiding usual radiation side effects and is preferred for pediatric cases.
