The latest chapter in radiation treatment
Every person's tumor is unique. At Mayo Clinic, one of the first decisions specialists make with you after your diagnosis is whether or not radiation is appropriate. If so, Mayo Clinic offers a wide range of radiation treatments, including radioactive implants (brachytherapy), traditional radiation (photons) and proton beam. For many people, strategically administered conventional radiation is the best treatment. But others require a different form of radiation, especially those with tumors next to and in vital organs, those who are sensitive to radiation's side effects, and children, whose tissues are still developing.
At Mayo Clinic, you'll work with your doctor and a team of specialists dedicated to developing an individualized plan that is best for your specific needs. Together, you will plot a treatment course that ensures that you receive the treatment with the highest success rate and fewest side effects.
Mayo Clinic specialists have a wide range of therapies available to you, based on your condition, needs and, in some cases, genetics. Choices include surgery, chemotherapy, traditional radiation and proton beam therapy. You may receive one or a combination, depending on your needs.
If your treatment calls for radiation, you are far from alone. More than half of all people with cancer receive radiation therapy. The reason is simple: It's effective. Radiation directs intense energy at cancer cells to destroy the genetic material that controls cell growth.
Unfortunately, radiation affects both healthy and cancerous cells. So the doctor using conventional radiation therapy (X-rays) has to balance killing cancer cells with preserving healthy ones. As a result, doctors often reduce the optimal X-ray radiation dose required to kill cancer cells.
Proton beam therapy offers an alternative.
More radiation, with less risk
Traditional X-ray treatment delivers radiation to everything in its path. That means tissue in front of and behind the tumor receives some damaging radiation. Most adult bodies can absorb and repair such collateral damage. But if your tumor is next to or in a vital organ, such as your brain or heart, traditional radiation can pose additional risks.
Traditional radiation isn't ideal for children either. Their organs are still developing, and damaging them with radiation can cause health issues later in life, some of which are growth problems, hearing and vision loss, heart disease, and additional cancers.
Proton therapy is more precise.
It uses the positively charged particles in an atom (protons) that release their energy within the target: the tumor. There is small amount of entrance radiation, but virtually none travels beyond the tumor. Because proton beams can be much more finely controlled, specialists can safely deliver higher doses of radiation to tumors.
Proton therapy is beneficial in the treatment of many kinds of tumors, including brain, breast, esophageal, eye, gastrointestinal, gynecological, head and neck, liver, lung, lymphoma, prostate, soft tissue, spine, and many pediatric cancers.
Proton beam therapy can treat a wide range of conditions, depending on the tumor type and the person.
At Mayo Clinic, you'll work with a team of specialists to develop the treatment that has the best success rate based on your specific cancer and your distinct needs. Proton beam therapy is just one weapon in a larger arsenal of treatment options.
In specific cases, specialists at Mayo Clinic may decide that proton beam is the best course of action to treat one of the many conditions listed below.
The Proton Beam Therapy Program is directed by the Mayo Clinic Cancer Center, the only National Cancer Institute-designated comprehensive cancer center in the country with a multisite presence, with locations in Arizona, Florida and Minnesota.
Mayo Clinic's proton beam program incorporates advanced techniques, such as biological dose modeling to ensure you get the exact amount of radiation you need and in-room image guidance to deliver it exactly where you need it. Mayo Clinic experts also use adaptive planning. After each session, a specialist examines how your tumor changes so your next treatment can be adapted to precisely target its new shape.
For people with tumors in or near their lungs, Mayo Clinic's proton program uses an advanced technique called gating. The technique images the lungs during breathing and delivers radiation only when the lungs are at a specific point in the respiratory cycle, ensuring that only the tumor — and not healthy lung tissue — receives radiation.
Mayo Clinic's proton program uses only pencil beam scanning, the most precise form of proton delivery. The pencil beam conforms more closely to the tumor, so specialists can "paint" small spots of protons back and forth through a tumor. The accelerated protons fill the depth and contour of the tumor. The precision of pencil beam scanning makes it especially beneficial in treating tumors adjacent to critical and sensitive organs and structures, such as the brain, eye and spinal cord.
At Mayo Clinic, you'll be cared for by a team of specialists from different fields who work together to determine your treatment options. This team approach means your care is coordinated to meet your needs so that you receive the treatment that's best for you.
Having a multidisciplinary team of experts on your side means that all of your doctors are working toward the same goal. This is especially beneficial when it comes to coordinating complex treatment protocols involving multiple therapies.
Mayo Clinic is leading the way in developing strategies to reduce the number of treatments needed for specific kinds of cancer. For instance, when you're prescribed a radiation dose, it's broken down into small increments called fractions. Breast cancer treatment can be divided into 25 fractions. Prostate cancer treatment can be more than 35.
Through research into the power of proton beams, Mayo Clinic experts are finding ways to reduce breast cancer treatment to between three and five fractions and prostate cancer treatment to five. That shortens the length of treatments from up to two months to one or two weeks.
Mayo Clinic researchers also monitor all proton beam therapy patients and gather data about side effects, tumor control, well-being and more. Researchers use this large database to develop better delivery techniques, care models and services for people with cancer.
Scientists at Mayo Clinic are also developing a new way to use proton therapy — stereotactic body and brain radiosurgery (SBRT). This advanced technique will allow Mayo Clinic doctors to treat tumors too risky to remove through surgery because of their size and location.
Unfortunately, today's best cancer treatment protocols don't yet meet the needs of every person with cancer. To help these patients, Mayo Clinic works with partners across the nation to conduct clinical trials that use experimental treatments. This partnership between institutions and patients can have an immediate impact while developing more-effective treatments options for the future.

How does Mayo Clinic decide which patients receive proton beam therapy?
The Mayo Clinic Proton Beam Therapy Program is one of very few hospital-based programs in the United States. This means highly specialized radiation oncologists work in a multidisciplinary environment that considers all your needs. At Mayo Clinic, your radiation oncologist will have a full range of treatment options and provide guidance for optimal care.
Proton beam therapy will be the best option for certain patients and tumor types, while others may benefit from a different approach — another type of radiation therapy or no radiation at all. Mayo Clinic specialists will work with you to develop the most effective treatment options tailored to your individual situation.
What types of cancer benefit most from proton beam therapy?
Pediatric tumors are among the most beneficial to treat with proton beam therapy, as it imparts less damage to a child's still-developing organs. Tumors near the brain also can highly benefit from proton beam therapy because there is no exit radiation to cause additional tissue damage. However, a wide range of cancers may benefit from proton beam therapy, and your oncologist will work with you to develop the treatment plan most appropriate for your cancer and your needs.
Does Mayo Clinic treat pediatric cancers with proton beam therapy?
Yes. Children who have cancer are among those who benefit the most from proton beam therapy.
Today, many pediatric cancers have significant cure rates — some higher than 90 percent. Proton beam therapy is targeted and helps to spare healthy tissue from the effects of radiation. People who must undergo radiation therapy early in life are less likely to have long-term side effects and complications, such as secondary cancers, with proton beam therapy than with conventional radiation therapy.
How do I know if I'm a candidate for proton beam therapy at Mayo Clinic?
People who would like to be considered for proton beam therapy at Mayo Clinic must schedule an appointment for a radiation oncology consultation. Mayo Clinic doctors and other specialists will review your case and consult with you to discuss all treatment options. Together, you will develop a treatment course that best fits your needs and condition, whether that treatment is proton beam therapy or another option.
Do I need a referral from my doctor to be seen at Mayo Clinic?
You do not need a referral from a doctor. You can contact the Mayo Clinic Appointment Office and request a radiation oncology consultation.
