• Radiation therapy uses high-energy rays to destroy cancer cells.

How Does External radiation Therapy Work?

External radiation therapy, also called external beam radiation, delivers radiation through a machine outside the body. This focused energy damages the DNA of cancer cells, preventing them from growing and dividing. It’s a highly targeted process, minimizing harm to surrounding healthy tissue. The area being treated, and the dose of radiation, are carefully planned by a radiation oncologist, a doctor specializing in radiation therapy.
