MammoSite® High-Dose Rate (HDR) Radiation Therapy

MammoSite targeted radiation therapy works from inside the breast, directly targeting the area where cancer is most likely to recur. A radiation seed is delivered via a MammoSite balloon catheter as directed by the treatment plan. After each treatment, the seed is removed. No radiation remains in the breast in between treatments. MammoSite spares healthy tissue and organs from the effects of radiation and allows treatment to be completed in just 5 days instead of 5-7 weeks.

High-Dose Rate Brachytherapy

High-dose rate brachytherapy is used with certain cancers to avoid damaging healthy tissue, and may kill more cancer cells in fewer treatments. High-Dose Rate (HDR) treatments are where a radioactive source is placed through a catheter into the tumor or the cavity where the tumor was removed. The number of treatments can be drastically reduced for those patients. The patients that could benefit from this type of treatment are breast (Mammosite), gynecological and lung (Endobronchial Brachytherapy).
