It is a cancer treatment that involves using intense beams of energy to kill cancer cells. Almost always, this term refers to external beam radiation, but there are types of radiation that can take place inside the body.

Radiation can damage cells by destroying the genetic materials that control how a cell grows and divides. Radiation is more likely to kill cells that are dividing. The stage in which cells divide is called mitosis.

Radiation therapy often uses CT scans, which create pictures of the inner body using X-ray technology on a computer linked to the machine. Radiation treatment on the head will most likely require a mask. Why? To help the patient remain in the same position throughout the entire treatment.
