Protons can be controlled with greater precision than X-rays; this means that more energy goes into destroying your tumor and less radiation is delivered to surrounding healthy tissue.1 For this reason, proton therapy is particularly good for treating tumors near healthy organs, including melanoma of the eye. Treating a melanoma of the eye with proton therapy can reduce your radiation exposure to the brain, when compared to X-rays.
