Photon Beam Therapy


Photon Beam Therapy Overview

Photon beam therapy is a type of external beam radiation therapy that uses x-rays or gamma rays that come from a sophisticated machine called a linear accelerator. This type of radiation can be used to treat larger areas of the body, such as the main tumor and surrounding lymph nodes.

How Photon Beam Therapy Is Delivered

The radiation dose is delivered at the surface of the body and goes into the tumor and through the body.

Are There Different Types of Photon Beam Therapy?

The process of photon beam therapy is the same, but the strength of the beams and exact location is different for each patient depending on the location and aggressiveness of the cancer.
