Detailed explanation-1: -Radiation therapy is a type of cancer treatment that uses beams of intense energy to kill cancer cells. Radiation therapy most often uses X-rays, but protons or other types of energy also can be used. The term “radiation therapy” most often refers to external beam radiation therapy.

Detailed explanation-2: -Radiation therapy (also called radiotherapy) is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors. At low doses, radiation is used in x-rays to see inside your body, as with x-rays of your teeth or broken bones.

Detailed explanation-3: -What is radiation therapy? Radiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells. Your cells normally grow and divide to form new cells.

Detailed explanation-4: -The most common type of radiation therapy is external-beam radiation therapy. It delivers radiation from a machine outside the body. It can be used to treat large areas of the body, if needed. A machine called a linear accelerator, or linac, creates the radiation beam for x-ray or photon radiation therapy.
