Description

also called HDR brachytherapy. A form of treatment that puts a radioactive source into small plastic tubes or applicators near the cancer. The radioactive source is put in the applicators and taken out a few minutes later. The applicator may be left in place. This is usually repeated for a few days to a few weeks and may be used along with external beam radiation therapy. This is different from low-dose rate brachytherapy, which uses lower doses of radiation over a longer period of time and leaves the radioactive seeds in the body. Compare to low dose rate brachytherapy. See also brachytherapy, external beam radiation therapy.
