Brachytherapy - Definition

Ask a question


Brachytherapy is a therapeutic technique similar to radiation, and is differentiated by hyper-localized radiation, thereby reducing the exposure to the radiation area. The idea is to get a radioactive element in the body, if possible directly inside the cancer to be treated (interstitial brachytherapy) or, if this is not possible, as close to the tumor as possible (in a cavity such as the uterus). The flow as well as duration of exposure are prepared in advance and the material used can be left in place to deteriorate gradually, or it can be withdrawn. Brachytherapy is mainly used in some prostate, uterine and breast cancers.
