Proton therapy is a form of external beam therapy for which powerful equipment is used to generate beams that penetrate the body. Oncologists use proton therapy to precisely deliver high doses of radiation to a tumor to kill the cancerous tissues without damaging surrounding healthy tissues.
In traditional radiation therapy, X-ray beams are typically used to treat cancer. The X-ray beams go through the cancerous tissue (tumor) destroying both healthy and cancerous areas along the path of the beam. Proton beams enter the body and deposit most of their energy at the target – the site of the tumor. Radiation oncology physicians are able to focus the energy of the proton beam within a tumor, minimizing damage to nearby healthy tissues and vital organs.
Choosing the right partner for cancer care really does make a difference. The fact is, people who choose MD Anderson over other hospitals and clinics often have better results.

No, proton therapy is neither experimental nor investigational. It has been used in the United States for more than 50 years and in a hospital setting since 1990. It is an established form of treatment that is widely accepted by physicians, government agencies and many insurers.
Proton therapy benefits patients whose tumors are solid with defined borders, meaning that the cancer has not spread to other parts of the body.
The MD Anderson Proton Therapy Center provides the most advanced radiation therapy available to treat cancers of the prostate, lung, liver, esophagus, brain, and lymphoma. Pediatric cancers such as sarcomas and cancers of the central nervous system such as brain tumors, as well as other rare tumors can also benefit from proton therapy. The team at MD Anderson Proton Therapy Center has a deep level of expertise in cancer and in the research and treatment of cancer with proton therapy. Because of this, we have been able to expand the areas treated with proton therapy to benefit even more patients who are fighting cancer.
After an initial consultation with a radiation doctor and radiation oncology nurse, patients undergo a simulation. The simulation is a treatment planning session during which the simulation team marks the specific areas where you will be treated during your proton therapy treatments.
Proton therapy treatments usually begin five to 10 business days after the simulation procedure and continue daily, Monday through Friday, for up to eight weeks. The length of treatment varies depending on the type of cancer. Your health care team will be able to tell you exactly how many treatments you will need after your consultation.
In the treatment room, the radiation therapist will position you and use the markings from your simulation procedure to deliver your prescribed proton therapy dose accurately. During your treatment, the radiation therapist will remain in the control room where he or she can see and talk to you at all times by closed circuit television and two-way intercom. Proton therapy treatment is painless, and most patients continue to work and exercise during and just after treatment.
Proton radiation, once delivered to the targeted tumor site, has a very short life. After you complete treatment, you can leave the treatment room without any risk or radiation exposure to others.
Yes. Many times lung cancer, pediatric cancers and lymphomas are treated with other types of therapy as well as proton therapy. Depending on the case and type of cancer, proton therapy may be used in combination with traditional radiation therapy, chemotherapy and surgery. If your type of cancer can best be treated with combination therapy, your doctor will discuss this in detail with you.
Yes. The ability to precisely target tumors makes proton therapy ideal for treating childhood cancer. It provides accurate treatment of tumors near or within sensitive organs while limiting radiation exposure to healthy tissues, which is vital in children whose bodies are still growing and developing. This may reduce side effects during treatment, often allowing children to better tolerate proton therapy. Tumors in children that can benefit most from proton therapy are tumors of the brain, head, neck, spinal cord, heart or lungs.
