What is 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.
What are the advantages and disadvantages of proton therapy?
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 is proton therapy?
Proton therapy is an advanced and highly precise radiation treatment for tumors. Compared to other methods, it focuses more energy on the tumor itself with less radiation to surrounding healthy tissue.
Where does proton therapy take place?
The proton treatment takes place in a special room . In some centers, a large mechanical arm called a gantry can move the beam around you as you lie on a table. This helps the radiation therapists treat the tumor from several angles.
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.
How do doctors and physicists work together?
When treating a patient, doctors and physicists work together to focus the proton beam on the exact size and shape of the tumor. The beam kills the tumor cells layer by layer, sparing surrounding healthy tissue.

Proton therapy is an outpatient procedure. Most patients are treated over a course of several sessions, and some treatments take longer than others. Currently, the proton beam is only available in a few specialized centers.
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.
What are the benefits of protons?
Proton therapy reduces overall toxicity, improves quality of life during and after treatment and increases the long-term survival rates for certain tumors.
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.”.
What to expect before proton therapy?
Before your first proton therapy treatment, you will have a consultation with the radiation doctor who will manage the proton therapy treatments and a radiation oncology nurse. During this visit, the doctor will examine you and explain the treatment options that he or she recommends for you.

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.

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 does proton therapy work?
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. 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.#N#Proton therapy typically involves the same number of treatments and the same session times as conventional radiation therapy.
How is protons 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.
What is the number to call for proton therapy?
To find out if you might be a candidate for proton therapy, you can call 833-319-1577. 3.
What cancers can be treated with proton therapy?

Why do we need proton therapy?
Why Choose Proton Therapy. Radiation is delivered directly into the tumor and stops, maximizing cancer cell dosage and minimizing damage to healthy tissue. With no exit dose, surrounding healthy tissue and organs are spared from radiation. Both short and long-term side effects are minimized.
How does proton therapy work?
Like standard X-ray radiation, proton therapy destroys cancer cells by preventing them from dividing and growing. But unlike the photons used in standard radiation therapy, proton therapy uses positively charged atomic particles—known as protons— to target cancer cells with greater accuracy and no exit dose.
What is the difference between protons and standard radiation?
Proton therapy and standard X-ray radiation are both types of radiotherapy that destroy cancer cells by preventing them from dividing and growing. The difference, however, is in their delivery. Protons are subatomic particles that can be controlled to deliver their radiation at exact depths.
What is a PBS scan?
Pencil Beam Scanning (PBS) is a revolutionary technology that boosts accuracy with its ultra-narrow proton radiation beam. Pencil Beam Scanning effectively ‘paints’ the tumor with radiation in three dimensions by moving a proton beam of pencil-point sharpness back and forth across each layer of the tumor.
How does X-ray radiation work?
Standard X-ray radiation beams, on the other hand, release radiation from the moment it penetrates the skin all the way through to the other side of the tumor. With radiation interacting with healthy cells throughout the beam’s path, the potential for damage to surrounding tissues and organs is greater.
When was proton therapy first used?
Food and Drug Administration (FDA) approved proton therapy as a radiation treatment option in 1988. To date, more than 180,000 people worldwide have received proton therapy at cancer centers in Europe, Asia, and the United States.

Proton therapy is an effective treatment option for adults and children with specific types of cancer. Protons are most successful in treating solid tumors with well-defined borders that have not spread. It is most often used for tumors of the brain, head, neck, lungs and spine.
How does proton therapy work?
Both proton therapy and traditional radiation treat tumors in the same way: by either killing cancer cells or inhibiting their growth. The most significant difference between the two is that proton beams travel to a specific depth and then stop, rather than continuing through the body.
Where are photons deposited?
The photons’ lack of charge and mass means most of their energy is deposited in normal tissues near the body's surface, as well as areas of the body beyond the site of the cancer. Similar to conventional high energy X-rays, proton therapy is an external beam radiation therapy technique.
