BRACHYTHERAPY FOR BREAST CANCERS
Brachytherapy for the treatment of breast cancer involves the insertion of a small device containing radioactive material into the breast tissue. The radioactive material works by destroying the cancer cells in the tissue. There are two types of brachytherapy that are typically used for the treatment of breast cancer: interstitial and intracavitary. During interstitial brachytherapy, several small catheters are inserted into the area of the breast where the cancer has been removed. Radioactive material is placed in the catheters, which are left in the body for short periods of time. During intracavitary brachytherapy, a small device is placed in the breast tissue, through which radioactive material is passed. The device stays in the body for as long as the treatment is necessary.
