MammoSite® RTS for breast cancer

Advantages of MammoSite RTS for breast cancer

MammoSite® Radiation Therapy System (RTS) is a form of brachytherapy targeted specifically for breast cancer treatment. MammoSite RTS involves using a catheter to place radioactive pellets (seeds) directly to the area where a breast tumor has been surgically removed via lumpectomy.

Some advantages of MammoSite RTS for breast cancer include:
  • MammoSite RTS calls for a single balloon catheter to administer radiation treatment. Standard breast brachytherapy involves surgically implanting up to 24 catheters into the breast.
  • By delivering internal doses of radiation directly to breast tumors, MammoSite RTS may help avoid damage to surrounding healthy breast tissue and may reduce some of the side effects associated with external beam radiation therapy.
  • With its precise, site-specific approach, this form of breast cancer radiation therapy may be completed in as few as four or five days, compared to seven weeks for traditional external beam radiation therapy.
