What Is Proton Therapy?

Proton therapy is a type of radiation therapy that uses protons to treat tumors. It is just as effective as traditional radiation therapy, with one major advantage: greater precision. Proton radiation can attack the tumor but avoid healthy tissues and organs nearby. This reduces the risk of treatment-related side effects and long-term complications.

Doctors may use proton therapy alone, or they may combine it with other treatment methods, such as traditional radiation therapy, surgery, chemotherapy and immunotherapy.
