what is proton beam treatment

Explore

Proton therapy, or proton beam therapy, is a type of radiation treatment that uses a beam of protons to deliver radiation directly to the tumor. Imagine a 196-ton, cancer-killing machine that can target a patient’s tumor with a sub-millimeter precision while sparing nearby healthy tissues and minimizing side effects.

What are the side effects of proton beam therapy?

Aug 01, 2017 · Proton beam therapy for cancer is similar to radiation therapy but uses high energy protons instead of photons or X-rays to damage tumors. It is usually used for early-stage tumors (stage I, II, and III) and has been used for many different types of cancer, such as lung cancer, prostate cancer, childhood cancers, and more.

Proton radiation treatment, or proton beam therapy, is the most precise and advanced form of radiation therapy available today. It is a painless, non-invasive treatment that allows patients to maintain their quality of life and quickly resume normal activities.

What hospitals have proton therapy?

Proton beam therapy is a type of external beam radiotherapy. Proton beam therapy is only suitable for a small number of people. It is used to help reduce the risk of long-term side effects that can sometimes develop after standard radiotherapy. It can also be used to treat cancers that are close to important structures in the body.

Is proton therapy safer than traditional radiation?

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. As part of the treatment, also called proton beam therapy, doctors direct cancer-fighting energy to precise locations within the body.

What does proton beam therapy do?

Proton beam therapy enables a dose of high energy protons to be precisely targeted at a tumour, reducing the damage to surrounding healthy tissues and vital organs which is an advantage in certain groups of patients or where the cancer is close to a critical part of the body such as the spinal cord.

How many treatments do you need for proton therapy?

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. Sometimes, doctors deliver proton therapy in 1 to 5 proton beam treatments. They generally use larger daily radiation doses for a fewer number of treatments.

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 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.

How long does radiation treatment take?

What is the difference between radiation therapy and proton therapy?

Proton therapy and conventional radiation therapy are both prescribed by radiation oncologists. One of the most obvious differences is the locality of treatment . Proton therapy accurately targets very specific locations, which may result in less damage to surrounding tissues. Conventional radiation therapy is less targeted, and more "normal" cells in the region of a tumor may be damaged. 3 

Can proton beams cause cancer?

Like most cancer treatments, proton beam therapy can cause side effects and complications. Even though proton beam therapy is delivered to a precise area, damage to normal cells near the tumor may occur.

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 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.
