Fight Cancer with
Proton Therapy
Radiation Treatment

If you have been diagnosed for the first time, or are facing recurrent cancer, proton therapy may be your best option as one of the world’s safest and most effective cancer treatments.

Proton therapy is a much less invasive alternative, recommended for numerous types of cancers that historically have been treated through traditional approaches such as surgery, chemotherapy and X-ray radiation. Located in San Diego, California Protons Cancer Therapy Center is at the forefront of medical care, research and biotechnology. With decades of combined proton experience, our world-renowned doctors leverage revolutionary cancer-fighting treatments and tools to treat both common and very rare cancers.

Revolutionary
Tumor Radiation Treatment

Precisely delivered within 2 millimeters, our intensity-modulated pencil beam scanning technology, offered in all five treatment rooms, releases a high dose of cancer-killing radiation that conforms precisely to the unique shape and size of the tumor. This highly targeted technology attacks the tumor with laser-like precision, while sparing surrounding healthy tissues and organs.

Renowned

Home to one of the world’s most experienced radiation oncology teams in the proton therapy treatment space, our doctors are internationally recognized and sought out by patients from around the world.

Is Proton Therapy
Right for Me?

Proton radiation therapy can be used exclusively, or in combination with surgery and chemotherapy, to treat numerous types of cancers and tumors, including but not limited to:

Proton Therapy vs.
Standard X-Ray Radiation

Standard X-ray radiation and proton therapy are both types of “external beam” radiotherapy. However, the properties of each are very different and result in varying levels of radiation exposure to the tumor site and surrounding tissues and organs.

Success Stories

I wanted to live a long life and didn’t want to risk having a heart attack or heart damage, so I chose proton therapy. After my consultation with Dr. Chang, I just knew that California Protons is where I wanted to be. He spent so much time with me and I felt very confident in his ability.

Proton therapy was a ‘game changer.’ Not a day goes by that I don’t think how fortunate we were to live six miles away from one of the best proton centers in the world. The entire staff is amazing. Compassionate, knowledgeable and the follow-up was incredible.

I have experienced absolutely no side effects from my treatments. I coached my men’s and women’s cross-country teams throughout my treatments, without missing a single day. I’ve maintained the intimacy I value so much with my wife, JoAnn, and remain active as a father and mentor in the community.

Prostate Cancer Patient
We chose proton therapy because of its ability to safely penetrate into the brainstem to reach a part of the tumor that couldn’t be touched before. And since the technology at California Protons is the newest and most advanced in the country, we thought ‘why go anywhere else?'
