Dr. Andrew Chang is a radiation oncology specialist with expertise in pediatric oncology and proton beam radiation oncology.

As a member of the Proton Therapy team, Dr. Chang provides proton beam radiation for the treatment of cancerous and non-cancerous tumors. The precise delivery of proton energy limits damage to healthy surrounding tissue, which may result in minimal or no side effects.

Before joining Scripps, Dr. Chang was a radiation oncologist at Hampton University Proton Therapy Institute in Virginia, where he developed a pediatric oncology program. He also served as the director of pediatric radiation oncology at the Indiana University Health Proton Therapy Center in Bloomington, Ind., and is an assistant professor of clinical radiation oncology at Indiana University in Indianapolis.

Dr. Chang has completed extensive research in the field of proton therapy for pediatric patients, stereotactic radiosurgery and pediatric chordoma, a rare cancerous bone tumor that occurs along the spine or the base of the skull.
