Proton beam therapy

Archives of Disease in Childhood, 2016
Cancer therapy is a multi-modality approach including surgery, systemic or targeted chemotherapy, radiation (external beam or radionuclide), and immunotherapy. Radiation is typically administered using external beam photon therapy. Proton therapy has been around for more than 60 years but was restricted to research laboratories until the 1990s.
