Radiation Therapy

Radiation therapy (sometimes called radiotherapy or irradiation) is a type of cancer treatment that uses high-energy waves of x-rays delivered by a machine called a linear accelerator. In high doses, radiation kills cells or keeps them from growing or dividing.

 

Radiotherapy can be used alone or in combination with chemotherapy and/or surgery to treat many kinds of cancer. Radiation oncologists work closely with medical and surgical oncologists to tailor treatment to each patient’s specific needs, based on the type of cancer, its location, and size.
