SEOR recommendations on the use of protons.

Abstract

Radiotherapy is one of the fundamental strategies in the treatment of cancer that is used in more than 60% of patients with this disease. It can be used with curative intention or to alleviate symptoms, always trying to minimize toxicity in healthy tissues. In “classical” radiotherapy, essentially photons are used. Proton therapy (PTR) is a special modality of radiotherapy that uses heavy particles (protons) instead of X-rays. These particles stand out above all due to their characteristic dose distribution in the tissues they pass through, with the maximum dose being deposited before their arrest, what is called Bragg’s Peak
