This method has proven most useful in cases where the cancer is located in hard-to-reach areas or near important CNS centres, making surgery more dangerous.ĭue to the unique advantages of the method, paediatric cases are among the main indications for proton therapy for cancer. Proton therapy allows doctors to destroy or shrink tumours without surgery. This has two main effects:ĭoctors can use higher doses of radiation because they can worry less about the preservation of healthy tissue īecause of the lower exposure of healthy tissue, patients deal with fewer side effects, which is particularly relevant for children. Whereas classic radiotherapy affects all the tissues through which the beam passes on its way to the tumour, proton therapy releases energy only on the target area. The difference between the two methods lies in the way energy is released during the movement of the beam. Proton therapy is a type of radiation therapy that uses small particles called protons instead of photons, as in ordinary radiation therapy.
