Proton Therapy

Rady Children’s Proton Therapy Program

Rady Children’s, in partnership with California Protons, offers proton therapy for pediatric cancers and non-cancerous tumors. We are the only program in California providing the most advanced proton therapy for pediatric brain and central nervous system tumors.

Pediatric radiation oncologists Andrew L. Chang, M.D., department chief of pediatric cancers at California Protons, and pediatric radiation oncologist Iain MacEwan, M.D., work with a team that includes certified pediatric oncology nurses, radiation therapists, medical dosimetrists, medical physicists and pediatric anesthesiologists.

Pediatric patients, both here in San Diego and referred from out of the area, are followed by our Neuro-Oncology team during their treatment. The 102,000-square-foot California Protons Cancer Therapy Center has the capacity to treat approximately 2,400 pediatric and adult patients annually.
