We're here for you
We know this can be an uncertain and anxious time for patients, and we’re here to help. At MD Anderson, our team of oncology experts takes a team approach to create the best possible treatment plan for each person’s individual cancer and situation.
How proton therapy works
A machine called a synchrotron or cyclotron speeds up protons. The high speed of the protons creates high energy. This energy makes the protons travel to the desired depth in the body. The protons then give the targeted radiation dose in the tumor.
What to expect
People usually receive proton therapy in an outpatient setting. This means they do not need to have treatment in the hospital. The number of treatment sessions depends on the type and stage of the cancer.
Treatment planning
Proton therapy requires planning. Before treatment, you will have a specialized computed tomography (CT) or magnetic resonance imaging (MRI) scan. During this scan, you will be in the exact same position as during treatment.
Receiving treatment
People receive proton therapy in a special treatment room. For each treatment, a member of the health care team will place the person into the device on the treatment table in the room. For some areas around the head and neck such as the eye, the person is positioned in a special chair, instead of on a table.
Time needed for each treatment
In general, a proton radiation treatment lasts about 15 to 30 minutes, starting from the time you enter the treatment room. The time will depend on the part of the body being treated and the number of treatments. It will also depend on how easily the team can see the tumor site with x-rays or CT scans during the positioning process.
Side effects
The treatment itself is painless. Afterwards, you may experience fatigue. You may also have skin problems, including redness, irritation, swelling, dryness, or blistering and peeling.
Cancers treated with proton therapy
Proton therapy is useful for treating tumors that have not spread and are near important parts of the body. For instance, cancers near the brain and spinal cord. It is also used for treating children because it lessens the chance of harming healthy, growing tissue. Children may receive proton therapy for cancers of the brain and spinal cord.
