Learn what it means to receive proton therapy in this short animation. Proton therapy is an advanced form of radiation therapy designed to kill cancer cells. It involves the use of charged particles called protons rather than the x-rays that are used in conventional radiation therapy.

How is proton therapy delivered?

Proton therapy is delivered by a device called a cyclotron, which sends a high-energy beam of protons through the skin toward the tumor. At Memorial Sloan Kettering, the first step is a CT or MRI scan to map the tumor in three dimensions. Then our radiation oncologists, in close collaboration with medical physicists, use computer programs to calculate how to deliver the treatment at the precise dose and location.#N#You will receive proton therapy in a special treatment room, where you will be positioned on a treatment table. An immobilization device will make sure you stay in the exact position on the table.

Does proton therapy reduce side effects?

With proton therapy, all energy has been released by the time it reaches the tumor site, so there is no dose beyond that point. This can help to reduce side effects. Proton therapy typically involves the same number of treatments and the same session times as conventional radiation therapy. Back to top. 6.

How do proton beams work?

How does proton therapy work? 1 The proton begins its journey at the ion source. Within fractions of a second, hydrogen atoms are separated into negatively charged electrons and positively charged protons. 2 The protons are injected via a vacuum tube into a linear accelerator and in only a few microseconds, the protons’ energy reaches 7 million electron volts. 3 Proton beams stay in the vacuum tube as they enter the synchrotron, where acceleration increases their energy to a total of 70 million to 250 million electron volts, enough to place them at any depth within the patient’s body. 4 After leaving the synchrotron, the protons move through a beam-transport system comprised of a series of magnets that shape, focus and direct the proton beam to the appropriate treatment room. 5 To ensure that each patient receives the prescribed treatment safely and efficiently, the facility is controlled by a network of computers and safety systems. The gantry can revolve 360 degrees, allowing the beam to be delivered at any angle. 6 As protons come through the nozzle, a custom-made device (the aperture) shapes the beam of protons, and another custom-made device (the compensator) shapes the protons into three dimensions, delivering them to the depth of the tumor. 7 At maximum energy, a proton beam travels 125,000 miles per second, which is equivalent to the two-thirds the speed of light. 8 From the hydrogen canister to the patient, a proton typically travels 313,000 miles.

What is the advantage of proton beam therapy?

The advantage of proton therapy (also called proton beam therapy) is that the physician can control where the proton releases the bulk of its cancer-fighting energy. As the protons move through the body, they slow down and interact with electrons, and release energy. The point where the highest energy release occurs is the “Bragg peak.”.

How long does radiation treatment take?

The first few days of treatment may take longer than the remaining sessions. You will usually come once a day, Monday through Friday, for up to eight weeks. The length of treatment varies depending on the type of cancer. You will see your radiation doctor once a week during the course of your treatment.

How does protons work?

How Proton Beam Therapy Works. Proton therapy is an advanced form of radiation treatment that uses protons instead of X-rays. In regular radiation therapy, the beam of energy goes into the body, through the tumor, and out the other side. This “exit dose” of radiation might affect healthy tissue beyond the tumor.

Insurance provider rules differ about which cancers are covered and how much a person needs to pay. Talk with your insurance provider to learn more. 3 Not all cancers can be treated with proton therapy.

Why is proton therapy important?

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. It is also used for cancer of the eye, such as retinoblastoma and orbital rhabdomyosarcoma.

What is proton therapy?

Like x-ray radiation, proton therapy is a type of external-beam radiation therapy. It painlessly delivers radiation through the skin from a machine outside the body.

3. How is proton therapy delivered?

Proton therapy is delivered by a device called a cyclotron, which sends a high-energy beam of protons through the skin toward the tumor. At Memorial Sloan Kettering, the first step is a CT or MRI scan to map the tumor in three dimensions.

4. How long do proton treatments last?

Proton therapy treatments usually last about 30 minutes from the time you enter the treatment room to the time you leave.

5. How does proton therapy compare with other forms of radiation?

While proton therapy kills cancer cells through a process similar to that used in conventional x-ray radiation — by damaging their DNA. However, because of the unique physical properties of protons, doctors can are able to deliver radiation to a specific depth in the body.

6. What are the benefits of proton therapy?

Because the proton beams do not penetrate beyond the tumor, proton therapy reduces the risk of treatment-related side effects due to radiation damage to normal tissues. Proton therapy may also allow the use of a higher radiation dose to the tumor, maximizing the chance of destroying it.

What is proton beam therapy?

Are There Side Effects to Proton Therapy? Proton therapy, sometimes called proton beam therapy, is a type of radiation used to treat cancer. It uses tiny particles called protons to do the job that X-rays do in traditional radiation therapy.

How does protons work?

Is proton therapy good for cancer?

Scientists are researching new ways to use proton therapy. It’s especially good for tumors, either cancerous or benign, that haven’t spread and are located in tricky areas like near your brain, spine, or eyes. Doctors use it to treat cancers in children to avoid damage to healthy growing tissue.

How does proton therapy work?

X-rays can damage healthy tissue on their way into and out of cancer cells. Proton therapy sends the particles to the exact spot where they’re needed. It kills more cancer cells and less healthy tissue than other radiation treatments.

What is the difference between MRI and CT scan?

CT scans, which use X-rays to take pictures inside your body. MRI, which uses magnets and radio waves to create pictures of your insides. It’s important for you to lie completely still during the tests so the team can get accurate pictures of the tumor and surrounding area.

Is proton beam radiation safe?

A type of radiation treatment called proton beam radiation therapy may be safer and just as effective as traditional radiation therapy for adults with advanced cancer . That finding comes from a study that used existing patient data to compare the two types of radiation.

Does radiation damage tumors?

Traditional radiation delivers x-rays, or beams of photons, to the tumor and beyond it. This can damage nearby healthy tissues and can cause significant side effects. By contrast, proton therapy delivers a beam of proton particles that stops at the tumor, so it’s less likely to damage nearby healthy tissues.

Is proton therapy safer than radiation?

Some experts believe that proton therapy is safer than traditional radiation, but there is limited research comparing the two treatments. Plus, proton therapy is more expensive than traditional radiation, and not all insurance companies cover the cost of the treatment, given the limited evidence of its benefits.
