It is delivered by machine outside of the body It is delivered by machine outside of the body (external-beam radiation therapy). It can also (external-beam radiation therapy). It can also be delivered by radioactive material placed in be delivered by radioactive material placed in the body near the cancer. the body near the cancer.

Being treated with Radiation can also damage Being treated with Radiation can also damage normal cells as well as cancerous cells. normal cells as well as cancerous cells. Treatments are very carefully planned and Treatments are very carefully planned and preformed. preformed.
