Definition
Brachytherapy, derived from the Greek term for “close” therapy, refers to placing a radiation source in or close to the tumor region. In cervical cancer, brachytherapy is used to boost the tumor region of an intact cervix or to treat the vaginal cuff in some postoperative patients to allow a higher dose to the region with limited side effects. Specialized instruments are placed in and around the region to allow for implantation of the radioactive source. Commonly used radiation sources include cesium-137 in low-dose-rate brachytherapy and iridium-192 in high-dose-rate brachytherapy.
