How does radiation therapy work?
Special machines send high energy x-rays or particles to the cancer cells. This damages the genetic material within the cells so they can no longer grow and spread. Once this happens, the cancer cells die and the body naturally removes them. Normal cells can also be affected by radiation, but they are able to repair themselves in a way that cancer cells cannot.
