Particle therapy is a form of external beam radiotherapy using beams of energetic protons, neutrons, or positive ions for cancer treatment. The most common type of particle therapy as of 2009 is proton therapy. Although a photon, used in x-ray or gamma ray therapy, can also be considered a particle, photon therapy is not considered here. Additionally, electron therapy is generally put in its own category. Because of this, particle therapy is sometimes referred to, more correctly, as hadron therapy. Particle therapy works by aiming energetic ionizing particles at the target tumor. These particles damage the DNA of tissue cells, ultimately causing their death. Because of their reduced ability to repair damaged DNA, cancerous cells are particularly vulnerable to attack.…

Charged-particle radiation therapy is a type of external radiation therapy that uses a particle accelerator to fire high-energy particles (such as protons or carbon nuclei[1]) that kill cancer cells. This method causes less damage to nearby healthy tissue than traditional radiation therapy with high-energy X-rays due to the Bragg Peak effect. External beam radiotherapy or teletherapy is the most common form of radiotherapy. The patient sits or lies on a couch and an external source of radiation is pointed at a particular part of the body.…
