A type of external radiation therapy that uses a special machine to make invisible, high-energy particles (protons or helium ions) that kill cancer cells. This type of radiation may cause less damage to nearby healthy tissue than radiation therapy with high-energy x-rays.
What are examples of particle radiation?
Alpha particles, beta particles, neutrons, and positrons are examples of particulate ionizing radiation. Gamma rays and X rays are electromagnetic ionizing radiation.
What are the 3 types of radiation treatment?
Three common types of internal radiation therapy include:
- Brachytherapy involves radioactive material that is implanted in the body. …
- Intraoperative radiation therapy (IORT) is used to treat an exposed tumor during cancer surgery. …
- Stereotactic radiosurgery (SRS) is not actually surgery.

How effective is particle therapy?
After 3 years, 46% of patients in the proton therapy group and 49% of those in the traditional radiation therapy group were cancer free. Fifty-six percent of people who received proton therapy and 58% of those who received traditional radiation were still alive after 3 years.
What are the two types of radiation therapy?
There are two main types of radiation therapy, external beam and internal.
What types of radiation are harmful?
Gamma rays are the most harmful external hazard. Beta particles can partially penetrate skin, causing “beta burns”. Alpha particles cannot penetrate intact skin. Gamma and x-rays can pass through a person damaging cells in their path.
Can you see radiation particles?

Which is worse radiation or chemo?
A systemic treatment like chemotherapy or liquid radiation may have more off-target side effects than a local treatment. But local treatments that are administered only to the cancer site, like external beam radiation or solid internal radiation treatment, may have more extreme side effects in that area of the body.
Do tumors grow back after radiation?
Normal cells close to the cancer can also become damaged by radiation, but most recover and go back to working normally. If radiotherapy doesn't kill all of the cancer cells, they will regrow at some point in the future.
What are the side effects of photon therapy?
In general, common side effects of proton therapy include:
- Fatigue.
- Hair loss around the part of your body being treated.
- Skin redness around the part of your body being treated.
- Soreness around the part of your body being treated.
