Dear Amy: What is radiation therapy? — Naomi, Tucson, Ariz.

Dear Naomi: Radiation therapy is one form of treatment for people with cancer. When a person has cancer, normal cells can grow throughout the body causing illness. Radiation therapy is used to kill cancer cells. A person lies on an X-ray table so that the radiation therapist can identify where the cancer cells are in the body. Then a large machine delivers a dose of radiation. This is done daily, sometimes for several weeks, until the cancer cells have been killed. Visit www.kidshealth.org/kid/health_problems/cancer/radiation.html for more information about radiation therapy.
