Overview
Radiation therapy, also called radiotherapy, uses carefully targeted and regulated doses of high-energy radiation to kill cancer cells. Radiation destroys cancer cells through a process called ionization. Some cells die immediately after treatment, but most die because the radiation damages the chromosomes and DNA so that the cells can no longer divide and the cancer cannot grow.
Radiation therapy may be your only cancer treatment, or it may be used in combination with other cancer treatments, such as surgery and chemotherapy.
A radiation oncologist is a doctor who has advanced training in treating cancer with radiation. This doctor evaluates you, prescribes the radiation treatment, directs the treatment team, monitors your progress, and manages any side effects of the treatment. The radiation oncologist may also be involved in follow-up care after treatment is completed.
