Proton therapy
![](https://commons.wikimedia.org/wiki/Special:FilePath/MayoProton.jpg?width=300)
Proton therapy or proton beam therapy is a medical procedure, a type of particle therapy that uses a beam of protons to irradiate diseased tissue, most often in the treatment of cancer. Proton therapy's chief advantage over other types of external beam radiotherapy is that as a charged particle the dose is deposited over a narrow range and there is minimal exit dose.
