Abstract
Proton radiotherapy is a form of ionizing radiation treatment using accelerated protons. The basic physical property of proton radiation is that they deliver most of their energy at the end of their path in the tissue, which is final and its depth is given by the initial energy of the protons.
This leads to a dose distribution of radiation, which, compared to modern photon radiation Therapy, places less burden on healthy tissues, especially in the middle and low dose range. The first irradiation of the proton took place in 1954 and the method is technologically mature.
Indications are discussed - we describe indications most common in proton centres as well as published results.
