Proton Therapy for Cancer Treatment

Proton therapy can be used to treat many types of cancer in addition to other conditions typically treated with X-ray radiation.


The decision to use proton therapy is based on tumor stage, type and location. The medical team at Scripps Proton Therapy Center can help to assess whether proton cancer treatment is an option for you.


Carl Rossi, MD, medical director of Scripps Proton Therapy Center, discusses the numerous types of cancer and tumors that can be treated with proton therapy, including breast cancer and brain tumors, and how this treatment option can potentially minimize side-effects that other radiation treatments may produce years later.
