Radiation therapy

Radiation therapy is the use of high-dose x-rays or other high-energy rays to kill cancer cells. Radiation can be given from outside the body using a machine (external radiation therapy), or it can be given with the help of radiation-producing materials that are implanted inside the body (internal radiation therapy).

Radiation therapy can be curative (kills all cancer cells), prophylactic (reduces the risk of cancer spreading to the area to which it is given), or palliative (helps reduce suffering).
