What is Proton Therapy

Fight cancer with a more advanced, less invasive form of radiation treatment.


Proton therapy is an advanced form of radiation treatment that suits many types of cancers and tumor types. If a physician recommends radiation therapy as part of a patient’s cancer treatment, proton therapy is likely an option. Unlike common radiation treatments that use X-rays or photons such as IMRT and Cyberknife, protons have a unique physical property that allows radiation oncologists to precisely target a patient’s cancer and stop the protons inside the tumor, avoiding healthy tissue and organs. This decreases the likelihood of undesired and unnecessary side effects. In some cases, proton therapy even offers higher overall survival outcomes and lower recurrence rates than other forms of radiation treatment.

How does Proton Therapy work?


  • Proton therapy treats a comprehensive range of cancers and tumor types.

  • Proton therapy delivers less radiation to healthy tissue than other forms of radiation treatment.

  • Proton therapy can reduce short-term and long-term side effects, depending on the disease site being treated.

  • Proton therapy can treat recurrent tumors, even in patients who have already received traditional forms of radiation or surgery.

  • Therapy sessions are quick and have less impact on your quality of life, so you can get back to daily activities as soon as you leave each session.

  • In some cases, proton therapy offers higher overall survival outcomes and lower incidence rates of secondary tumors than other radiation treatments.

Why Proton Therapy is Different

Protons and X-rays both destroy cancer cells by preventing them from dividing and growing. Protons are energized particles that deliver radiation at exact depths to precisely target tumors. Because protons deposit a majority of the radiation dose at the tumor site and travel no further through the body, the surrounding healthy tissue is spared. X-rays, on the other hand, release their maximum dose of radiation quickly after penetrating the skin, potentially damaging healthy tissue and organs on their way to the tumor site and as they continue to pass through the body.

Treatment Plan - Oklahoma Proton Center


We opened in 2009 as the sixth proton center in the United States. As a result, our clinical team has treated thousands of patients and is one of the most experienced in the country. We believe cancer treatment should be approached in a patient-first manner, and we’ve built the Oklahoma Proton Center to provide access to innovative treatment in a healing, supportive environment.
