Margins Matter.

‘Get it all’ in your first lumpectomy with MarginProbe.

Doctors answer patients' questions about MarginProbe


MarginProbe helps surgeons assess margins in the operating room.

For breast surgeons, there are critical questions with every lumpectomy performed: Did I remove the right amount of tissue? Are the margins clean? Will I be able to tell my patient that we’ve removed all of the cancer? Did I do my job well?
The MarginProbe® System is a new technology to provide surgeons, for the first time, with the ability to perform an intraoperative margin assessment — a diagnostic procedure to better identify whether the tissue excised during the lumpectomy has positive margins. In approximately five minutes, within the operating room, surgeons can now have immediate information about the presence of cancer cells on the margins of the tumor.
Breast surgeons have said that this is the first significant advance in margin assessment in thirty years.
On December 28, 2012, the MarginProbe System received Premarket Approval by the US Food and Drug Administration.
