Radiation therapy

Also known as: External beam radiation therapy, X-ray therapy

External beam radiation therapy treatment, also called x-ray therapy, is directed at the tumor from a machine located away from your body, usually a linear accelerator. External beam is a painless, non-invasive process and can be given once or twice per day, depending on the treatment protocol being used. 

Treatments are usually scheduled as a series of outpatient treatments, five days a week from one to ten weeks. The number of radiation treatments depends on the size, location and type of cancer; the intent of the treatment; a patient’s general health; and other medical treatments the patient may be receiving. Patients are given a break from treatment on weekend days to give normal cells some time to heal, thus reducing side effects. A patient receiving external beam radiation therapy is not radioactive or dangerous to the people around him or her.
