Radiation is used to treat many types of cancer. The following are the three basic methods of treating cancer using radiation:

  1. External Beam
  2. Implant (brachytherapy)
  3. Radiopharmaceutical

External Beam Therapy (Radiation Oncology)

Linear accelerators are used to focus a beam of radiation on a cancer site. This type of treatment is done on an outpatient basis. Usually patients go to the Radiation Oncology department for a daily treatments over a 30 day period.

Safety concern: These patients do not become radioactive in any way and present no radiological hazard to anyone around them.
