Proton therapy is a kind of radiotherapy based on accelerating protons, which are the nuclei of hydrogen atoms, to high energy level before irradiation and concentrating dose on cancer cells. Since healthy tissues in the vicinity of the cancer cells are not negatively affected, it is possible to provide therapy with few side effects. Unlike surgical procedures, this is a gentle and less impact treatment that allows patients to be treated as outpatients and for this reason it is attracting attention around the world.
