About John Han-Chih Chang

I CHOSE OKLAHOMA PROTON CENTER BECAUSE... Radiation oncology is a treatment people in Oklahoma and the southwest cannot be without. Radiation centers like Oklahoma Proton Center provide the appropriate patients with the best possible cancer treatments. ABOUT ME When I was in 8th grade, my grandfather passed away from very advanced lymphoma despite the very best treatment at one of the best cancer centers in America. I vowed to make a difference. In college, I initially chose the path of a researcher working in laboratories looking for treatments to combat bladder and breast cancers. I began work with a radiation oncology resident who was doing his research year in the lab, and he convinced me to join him for a day in his clinic. The technology of radiation oncology was in its rapid growth phase at the time and I was hooked. I realized I could pair my passion for helping cancer patients with my love of technological advances. That launched my drive to be a physician and more specifically a radiation oncologist.
