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 oncologist Andrew L. Chang, M.D., department chief of pediatric cancers at California Protons, heads 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.

Advantages for Children

Proton therapy has been successfully used with children for more than 20 years. It is considered the ideal form of radiation for pediatric patients, as it provides a more precise approach to destroying certain tumors and cancers compared to conventional X-ray radiation.

The therapy involves the use of a controlled beam of protons to target tumors with control and precision unavailable in other radiation therapies. The targeted delivery of proton energy limits damage to healthy surrounding tissue and allows for a more potent and effective dose of radiation to be used. The pencil beam technology used at the center makes the delivery even more precise.

Less damage to the healthy surrounding tissue is especially important for children, as it means less damage to growing organs, such as the brain, heart and lungs. As a result, long-term complications associated with X-ray therapy are significantly reduced as well, such as growth and hormonal deficiencies and the risk of secondary cancers later in life.

The 102,000-square-foot California Protons Cancer Therapy Center has the capacity to treat approximately 2,400 pediatric and adult patients annually.
