Can proton therapy cause cancer?
Proton therapy can cause side effects as the cancer cells die or when the energy from the proton beam damages healthy tissue. Because doctors can better control where proton therapy releases its highest concentration of energy, proton therapy is believed to affect less healthy tissue and have fewer side effects than traditional radiation therapy.
