About Radiation Therapy

A powerful weapon against cancer

Radiation therapy is one of the most common cancer treatments for cancer. It uses special equipment to aim high doses of radiation at cancer cells. This damages the cancer cells and causes them to die. It can be given alone or used with other treatments, such as surgery or chemotherapy.

Unlike chemotherapy, which exposes the whole body to cancer-fighting drugs, radiation therapy is usually a local treatment. It targets only the part of the body being treated. The goal of radiation treatment is to damage as many cancer cells as possible, with little harm to nearby healthy tissue.

There are two basic types of radiation therapy: External Beam Radiation Therapy (EBRT) and Internal Radiation Therapy also called Brachytherapy. With EBRT, the radiation is delivered from outside of the body using one of several different types of radiation systems. For patients undergoing Brachytherapy, a radioactive source is temporarily or permanently implanted inside the body either in the tumor site or in a cavity left by a tumor that has been surgically removed.

Regardless of whether you and your Radiation Oncologist choose a form of External Beam Radiation Therapy or Brachytherapy, the primary objective of these increasingly sophisticated radiation therapy systems is to deliver as much radiation as possible — for maximum effectiveness — while minimizing damage to surrounding healthy tissue and possible side effects.
