Proton beam therapy
Proton therapy, or proton beam therapy, is a type of radiation therapy that uses a beam of protons (positively charged particles) to deliver radiation directly to the tumor while reducing the amount of radiation damage to healthy tissue, near a tumor. As the protons move through the body, they slow down and interact with electrons, and release energy.
The point where the highest energy release occurs is the “Bragg peak.” A physician can designate the Bragg peak’s location, causing the most damage to the targeted tumor cells. A proton beam conforms to the shape and depth of a tumor while sparing healthy tissues and organs.
