Radiation uses high energy x-rays to damage the cancer cells. When they cannot repair themselves, the cancer cells die. This helps healthy cells to grow back and the tissues to recover.
Radiation is considered a “local” treatment because it focuses on the tumor or cancerous area, not on other parts of the body. Radiation therapy given after surgery or another treatment, is called adjuvant therapy. Radiation is used in a safe and targeted way.

This noninvasive (does not involve inserting devices into the body) imaging device uses special x-ray equipment with sophisticated computers to produce multiple images or pictures of the inside of your body.
A linear accelerator delivers prescribed doses of radiation to the body from outside the body.
A noninvasive (does not involve inserting devices into the body) radiosurgery system that treats some cancerous and noncancerous tumors and certain other conditions – without the need for incisions.
If you are uncomfortable at any time during the treatment, let your team know. They can pause and restart the treatment when you are ready.
