In traditional radiation therapy, X-rays or gamma rays (gamma-knife) are commonly used to treat cancer. X-rays pass through the tumor tissue, damaging not only affected, but also healthy cells along the way. In proton therapy, the energy of a targeted beam of protons is used. The special property of protons is that they release most of their energy at the final point of the path to the tumor site, practically without damaging the tissues located before the neoplasm, and are completely safe for the tissues and organs behind it. This property of the proton beam allows doctors to direct radiation precisely on the target, reducing damage to surrounding healthy tissues and vital organs.
