MammoSite® brachytherapy treatment is administered to the tissue surrounding a tumor after a lumpectomy has occurred. At the time of surgery, an inflatable balloon is inserted with a catheter. The balloon fills the region that the tumor occupied. A treatment schedule often consists of 2 treatments a day over a span of 5 days. During this time, high doses of radiation are given to a very specific region while not threatening healthy tissue.
