brachytherapyImplant radiation, internal radiation, intracavitary therapy, interstitial radiation therapy Radiation oncology RT in which radioactive materials–iridium-192, radium-226, and other radioisotopes, sealed in needles, seeds, wires, or catheters are placed in direct contact with certain carcinomas to deliver locally intense ionizing radiation–eg, as needed in invasive CA of the uterine cervix. See Intravascular brachytherapy.
Radiotherapy in which the source of irradiation is placed close to the surface of the body or implanted in the tissues to be treated (e.g., application of radium to the cervix). Treatment targets specific tissues without harm to the surrounding normal tissue.
brachytherapyA form of RADIOTHERAPY in which sealed sources of radioactive material are inserted for various periods into body cavities or directly into tumours, so as to lie as close as possible to the area to be radiated.
A type of radiation treatment for cancer in which the source of the radiation is applied directly to the surface of the body.
