MammoSite® Brachytherapy for Breast Cancer

MammoSite® brachytherapy is a form of internal radiation therapy that is used following a lumpectomy (the surgical removal of a tumor from the breast). It is used either alone or with external beam radiation therapy to kill any remaining cancer cells after surgery.

How is MammoSite brachytherapy done?

Following surgical removal of your breast tumor:

What can I expect during MammoSite brachytherapy?

You will receive treatment on an outpatient basis.

During your treatment session:

After you complete your course of treatment (typically twice a day for five days), a radiation oncologist drains and removes the balloon so the cavity can heal.

What are the benefits of MammoSite brachytherapy?

MammoSite provides radiation directly to the tissue next to the removed cancer (the most likely place that new tumors would return), while traditional radiation treats the whole breast.

MammoSite treatment is also shorter than with traditional radiation therapy, which can last seven weeks.
