External beam therapy (EBT) is a method for delivering high-energy x-ray or electron beams to a patients tumor. Beams are usually generated by a linear accelerator and targeted to destroy cancer cells while sparing surrounding normal tissues. EBT also may be used to relieve symptoms in patients with advanced cancer or cancer that has metastasized.

To prepare for EBT, your doctor will perform a physical exam and use CT scanning to conduct a treatment simulation session. Other imaging procedures may be used to help determine the exact shape and location of your tumor, and a special device may be created to help you maintain the same exact position during each treatment. Your doctor will give you specific instructions based on the treatment technique to be used.
