High-dose rate brachytherapy involves placing a radioactive source of high strength directly into the tumor using specialized instruments. With the use of computerized treatment planning, physicians can vary the radiation dosage and placement, resulting in more precise treatment and potentially less harm to healthy tissue.

HDR brachytherapy allows highly localized doses of radiation to be delivered to the tumor quickly, each treatment takes approximates 10-15 minutes of actual treatment time. It may be used alone or with external beam radiation therapy to treat the cancer.

At Central Florida Cancer Care Center, HDR Brachytherapy is being used in the treatment of gynecologic, lung, skin, and breast cancers.
