Radiation therapy using X-rays has long been used to treat cancers and noncancerous (benign) tumors. Proton therapy is a newer type of radiation therapy that uses energy from positively charged particles called protons .
What is radiation simulation?
During radiation simulation, your radiation therapy team works to find a comfortable position for you during treatment. It's imperative that you lie still during treatment, so finding a comfortable position is vital. To do this, you'll be positioned on a table that will be used during your treatment.

Does proton therapy release energy?
Still, proton therapy does release some of its energy in healthy tissue. What side effects you experience will depend on what part of your body is being treated and the dose of proton therapy you receive. In general, common side effects of proton therapy include: Fatigue. Mouth, eating and digestion problems. Headaches.
Can proton therapy cause cancer?
Proton therapy can cause side effects as the cancer cells die or when the energy from the proton beam damages healthy tissue. Because doctors can better control where proton therapy releases its highest concentration of energy, proton therapy is believed to affect less healthy tissue and have fewer side effects than traditional radiation therapy.
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.
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.
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.

What is protons therapy?
Proton therapy is the most technologically advanced method to delivery radiation treatments to cancerous tumors available today. The unique characteristics of how protons interact within the human body allow it to deliver curative radiation doses while reducing doses to healthy tissues and organs resulting in fewer complications ...
Does radiation therapy reduce side effects?
This results in less healthy tissues and organs receiving unnecessary radiation thereby reducing unwanted complications and side effects. Standard radiation therapy utilizes x-rays which deposits the majority of the radiation dose immediately upon entering the body while traveling to the tumor.
Do cancer cells repair molecular damage?
While both normal and cancerous cells go through this repair process, a cancer cell’s ability to repair molecular injury is frequently inferior. As a result, cancer cells sustain more permanent damage and subsequent cell death than occurs in the normal cell population.

How do X-rays work?
To deposit the proper amount of energy into the tumor, X-rays must irradiate much of the healthy tissue in front of it. Then, they penetrate the tumor and irradiate much of the healthy tissue behind it. Protons interact in a very different way. They deliver a low dose to the healthy tissue then, at a precise depth, ...

To date, approximately 131,000 people worldwide have received proton therapy at centers in Europe, Asia and the United States.
Why are protons calibrated?
Protons can be calibrated to release the bulk of their energy at certain depths inside the body and conform to the shape of the tumor. This level of precision helps us place more radiation dose exactly at the spot of the tumor, focusing more energy on destroying the cancer while sparing nearby healthy tissue. 1.

For a proton to become electrically charged, it first needs to be separated from its electron partner in an atom, and then sped up. The faster that proton is moving, the more energy it will carry.
When was proton radiation first used?
Proton radiation was first suggested as a treatment for cancer in 1946 by physicist Robert R. Wilson, Ph.D. Early efforts to treat patients began in the 1950s, but it was limited to a few areas of the body. Since then, the use of proton therapy has grown, with 28 proton centers in operation in the United States alone.
How do protons work in cancer?
In the field, hydrogen atoms then separate into negatively charged electrons and positively charged protons. The protons travel through a vacuum tube within a pre-accelerator. This process boosts their energy ...
How do protons travel?
The protons travel through a vacuum tube within a pre-accelerator. This process boosts their energy to two million electron volts. The protons continue in the vacuum tube and begin their high-speed journey in the synchrotron. They travel around the synchrotron about 10 million times per second.
What is conformal proton radiation?
Therefore, conformal proton radiation therapy is used to treat the primary tumor, and is then followed by X-ray therapy to treat the regional nodes.
How does protons work?
That means a machine outside your body sends radiation beams through your skin and into the tumor and the area around it. Traditional radiation sends X-rays. Proton therapy sends positively charged atomic particles called protons .
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 affect cancer?
Proton therapy sends positively charged atomic particles called protons. They affect your tissues and the cancer cells in the same way as X-rays, but they’re more precise. 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.
How long should a proton therapy session last?
These marks may remain for a while to help the team position your body for each proton therapy session. Each session should be about 15 to 30 minutes. You’ll go to a special room where your treatment team will put you in the right position for a technician to aim the protons at the tumor.
Why do doctors leave the proton room?
The medical team will leave the room to protect themselves from the radiation. They’ll be able to see and hear you through a video system. Some proton therapy rooms have a large mechanical arm called a gantry that moves around you to send radiation at several different angles.
