MammoSite® Balloon

MammoSite targets radiation to the tissue adjacent to the lumpectomy site. The device places the radiation source inside the lumpectomy cavity (the space left when a tumor is removed) and delivers radiation to the area where cancer is most likely to recur.

Our physicians were among the first physicians to use the MammoSite balloon. FDA clinical trials for the MammoSite have shown it to be well tolerated, with mild side effects for a short period of time.

The therapy is given on an outpatient basis. No hospital stay is required. Treatment is twice a day (usually 6 hours between treatments). Treatments are painless and usually take about 10 minutes.

5-year clinical trial data for MammoSite shows:

  • no local recurrences
  • 82% of the patients had good/excellent cosmetic results
  • 100% of patients in the initial clinical trial would recommend MammoSite® to a friend or family member
  • 100% of patients in the initial clinical trial would use MammoSite® again if they had to do it over
