This treatment method delivers high doses of radiation from an external radiation source which specifically targets the affected area and minimizes the dose to the surrounding normal tissue. The process is known as external beam radiation therapy (EBRT).

EBRT uses a linear accelerator to direct radiation to the affected area.

External beam radiation therapy involves a series of daily outpatient treatments to accurately deliver radiation to the area at risk.

• Before beginning treatment, you will be scheduled for a simulation to map out the area being treated. This will involve having X-rays and/or a CT scan. You will also receive tiny tattoo marks on your skin to help the therapists precisely position you for daily treatment.
• Treatment is given once a day, Monday through Friday, for about six weeks.
