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 are the advantages and disadvantages of proton therapy?
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.

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.

Can protons make you tired?
After your session, you might feel tired. Proton therapy side effects are similar to those of other radiation treatment methods. Because the technique can mean less exposure to the radiation, side effects can be less than those of traditional radiation treatment.
Can you go home after proton beam?
After being treated with the proton beam, most people can go home and resume their activities. For certain tumors, your doctor might order tests to see how the treatment is affecting the tumor, and adjust your treatment if necessary.
Does radiation damage DNA?
Both regular and proton radiation therapy damage the DNA of cancer cells, but proton therapy has two main advantages: more energy focused on the tumor, and less radiation affecting healthy tissue nearby. With less healthy tissue affected by the radiation, side effects can be milder.
Is proton therapy expensive?
The machines and equipment for proton therapy are very complex and expensive to make and operate. It is important to check with your insurance provider about coverage. Some proton therapy centers have financial counselors to consult. Your doctor will recommend the appropriate treatment for your cancer.
What is proton therapy?
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.
Where is the Proton Center?

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.
What is MD Anderson Proton Therapy?
