brachytherapy

 [brak″e-ther´ah-pe]
internal radiation therapy using a radioactive source placed either within the body or a cavity, on the body surface, or a short distance from the surface.

brach·y·ther·a·py

(brak'ē-thār'ă-pē),
Radiotherapy in which the source of irradiation is placed close to the surface of the body or within a body cavity; for example, application of radium to the cervix.

brachytherapy

(brăk′ē-thĕr′ə-pē)
n. pl. brachythera·pies
Radiotherapy in which the source of radiation is placed close to the surface of the body or within a body cavity.
Radiation therapy 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 ionising radiation—e.g., as needed in invasive carcinoma of the uterine cervix

brachytherapy

Implant 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.

brach·y·ther·a·py

(brak'ē-thār'ă-pē)
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.

brachytherapy

A 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.

Brachytherapy

A type of radiation treatment for cancer in which the source of the radiation is applied directly to the surface of the body.
