Proton Therapy



Proton therapy is an effective form of radiation therapy for many types of tumors.  It destroys cancer cells by preventing them from dividing and growing, just like standard X-ray radiation, but offers many important benefits. The most significant one is that patients experience fewer short- and long-term side effects. Unlike x-rays, protons can be precisely controlled so that most of the radiation ends up directly in the tumor so less healthy tissue is damaged during treatment. Proton therapy also lowers the occurrence of secondary tumors which can occur many years after receiving radiation treatment.


Proton2Proton Therapy is particularly beneficial when tumors are located near critical organs or structures, such as the brain, heart or spinal cord. It is also an important treatment for children because their bodies are still growing and are more sensitive to the undesirable effects caused by radiation. The precision of protons reduces the risks of developmental and growth problems, as well as a potential reduction in IQ in pediatric patients.

Proton therapy is effective in treating many types of cancers as well as non-cancerous tumors. Tumor types that could often benefit from proton therapy include:


  • Proton3Brain
  • Head and neck
  • Base of skull
  • Central nervous system
  • Lung
  • Breast
  • Prostate
  • Pediatric
  • Tumor near the spine





ROC is the only physician group in Illinois to treat patients with proton therapy. ROC physicians have exclusive privileges to provide proton therapy at the Northwestern Medicine Chicago Proton Center, which has been treating patients since 2010. If you have been diagnosed with cancer and are considering proton therapy as a treatment option, you can visit for more information.

Concordia University men’s basketball head coach Tyler Jones comes from a strong family history of prostate cancer. “My dad had it, his brothers, and so did my older brother. When the doctor told me, it was a surreal day.”  That day was May 11, 2011. And thanks to the CDH Proton Center, A ProCure Center in Warrenville, by October of that same year, his treatment was complete. Read more
