Definition

External beam radiation therapy (EBRT) is a method for treating cancer using high-energy radiation from outside the body to target and destroy malignant cells. It utilizes beams of X-rays, gamma rays, or protons directed precisely at the tumor.

5 Must Know Facts For Your Next Test

  1. EBRT employs radioisotopes like cobalt-60 to generate high-energy gamma rays for treatment.
  2. Linear accelerators are commonly used in EBRT to produce X-rays for cancer therapy.
  3. The primary goal of EBRT is to maximize damage to cancer cells while minimizing exposure to surrounding healthy tissues.
  4. EBRT can be combined with other treatments such as chemotherapy and surgery for enhanced effectiveness.
  5. Fractionation in EBRT refers to delivering the total radiation dose in multiple smaller doses over several sessions.
