Introduction to Radiation Therapy

Radiation therapy is one of the many tools used to combat cancers. Radiation treatments utilize high-energy waves such as x-rays to kill cancer cells. Radiation can be used alone or in conjunction with other treatments (e.g. chemotherapy and surgery) to cure or stabilize cancer.

Like other therapies, the choice to use radiation to treat a particular cancer depends on a wide range of factors. These include, but are not limited to, the type of cancer, the physical state of the patient, the stage of the cancer, and the location of the tumor.
