   Radiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells. Your cells normally grow and divide to form new cells. But cancer cells grow and divide faster than most normal cells. Radiation works by making small breaks in the DNA inside cells.

   Radiation can be given off naturally, like from sunshine and, in low doses, from the earth and rocks. Radiation can also be produced artificially by machines. In lower doses, it is used for things like x-rays, to take pictures of the inside of your body. Radiation therapy to treat cancer uses much higher doses of radiation to destroy cancer cells.

The computer uses multiple angles to identify the best approach to kill the tumor and limit exposure to normal tissue. IMRT is used when a tumor is close to sensitive organs, such as with anal cancer where ...
