External Beam Radiation Therapy (EBRT) can be used in conjunction with surgery, chemotherapy, brachytherapy and a variety of other techniques used in cancer treatment.

What to Expect From External Beam Radiation Therapy

External beam radiation therapy is planned very carefully. The goal is to sculpt the radiation beam so only the tumor is affected and the surrounding healthy tissue is spared.

  • You undergo a series of computed tomography (CT) scans in order to accurately shape the radiation beam to match your tumor
  • Your skin is marked to show where the rays should be directed
  • During the treatment session, you need to lie very still so the radiation beam reaches only the affected area
  • The treatment session lasts between 10—15 minutes

There are side effects of radiation therapy, depending on the area being treated and the dose of radiation received. Side effects include hair loss, skin sensitivity and fatigue.
