External Beam Radiation Therapy (EBRT) is a common cancer treatment that uses high-energy rays to target and destroy cancer cells. The radiation is delivered from outside the body using a machine called a linear accelerator. This method allows doctors to focus the radiation precisely on the tumor while minimizing damage to surrounding healthy tissue. Patients typically receive EBRT in multiple sessions over several weeks. Each session lasts only a few minutes, and the treatment is painless. Before starting therapy, doctors perform imaging tests to determine the exact location and size of the tumor, ensuring accurate targeting during treatment.
