Proton therapy is an advanced treatment option that precisely delivers radiation to the size, shape and depth of your prostate. This approach allows your doctor to radiate the cancer while limiting damage to the surrounding tissue.

Target Your Prostate With Precision

More precision means less damage to healthy tissue in the urethra, bladder, bowel, and sexual organs than with traditional radiation, potentially offering fewer short- and long-term side effects and secondary cancers.

With conventional X-ray therapy, surrounding healthy tissue gets a considerable dose of radiation, which can lead to side-effects and secondary cancers down the road. With proton therapy, treatment is delivered precisely to the tumor, so less radiation is delivered to the surrounding healthy tissue.

With prostate cancer, you have a wide variety of treatment options that depend on who you are and what your cancer requires: options like surgery, chemotherapy, hormone therapy, radiation and more. Conventional radiation exposes surrounding healthy tissue to excess radiation, which can potentially lead to side-effects and secondary cancers down the road. With surgery, there is a greater chance of some serious side effects, such as incontinence. Proton therapy, delivers radiation precisely to the prostate, so less radiation is delivered to the surrounding healthy tissue.

Proton therapy takes advantage of a unique characteristic of protons—they deliver their maximum dose of radiation, known as the Bragg Peak, right before they come to a stop. That’s how the damage is concentrated on the cancer, protecting healthy tissue.

If you’ve been diagnosed with prostate cancer, the radiation oncology specialists at SCCA Proton Therapy Center are available to give a second opinion and determine if proton therapy is right for you.


Pencil-beam scanning allows treatment to conform the size, shape and depth of your prostate, “painting” on radiation accurate within millimeters.

Proton therapy may help preserve testosterone production and reduce the likelihood of secondary tumors in the future.

Treatments are safe and relatively painless for most prostate patients, helping speed recovery and maintain lifestyle.

Appointments typically take between 15-60 minutes, meaning no overnight stays and minimal interruption of your routine.

As of 2017, more than 130,000 people worldwide have received proton therapy at centers in Europe, Asia and the United States.

Proton therapy is often the only radiation treatment available if you’ve already received radiation for a previous cancer occurrence.
