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) 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.
It is more usually called Particle therapy. It may include or exclude electron therapy.
