Treatment Technology

MammoSite

When breast cancer is found early, “breast conservation therapy “-lumpectomy rather than a mastectomy- may be possible.  MammoSite is a Targeted Radiation Therapy that may be used following lumpectomy to help keep cancer from coming back.  Instead of the usual 6 ½ weeks of daily radiation treatment, treatment is completed in only 5 treatment days.

MammoSite uses a small, soft balloon attached to a thin catheter (tube) that is placed inside the lumpectomy cavity in the breast.  To deliver the radiation, a tiny source of radiation called a seed is placed within the MammoSite balloon by a computer controlled machine.  After each treatment the seed is removed and the catheter remains for the next treatment.  After 5 days of treatment, the catheter is removed and the area is closed with a small bandage. Most women say they feel little or no discomfort during or after the device is removed. Your doctor will carefully evaluate your cancer to determine if you are a candidate for this advanced treatment.
