Radiation Therapy
Radiation Therapy
Radiation therapy, also called radiotherapy, is a type of cancer treatment. This treatment uses beams of intense energy to kill cancer cells. Radiation therapy most often uses X-rays. But other types of radiation therapy exist, including proton radiation.Modern methods of radiation are precise. They aim beams directly at the cancer while protecting healthy tissues from high doses of radiation.
Radiation therapy can be given inside or outside of your body. The most common kind is external beam radiation therapy. This treatment uses a large machine called a linear accelerator. High-energy beams are aimed from the machine to a precise point on your body.
