What is radiation therapy?
In radiation therapy (also called radiotherapy), invisible high-energy rays are used to damage cancer cells and can stop them from growing and dividing. This ultimately can kill the cancer cells treated with radiation. A specialist in radiation therapy is called a radiation oncologist.
