The goal of lumpectomy surgery for breast cancer is to completely remove the tumor and have clear margins, reducing the rates of local recurrence. The MarginProbe® System is a new device that can detect microscopic tumor cells at or close to the margin of the surgical resection intraoperatively, providing the surgeon with the ability to re-excise tissue at the time of surgery, reducing the need for a second surgery to obtain clear margins.

At a Glance

  • Lumpectomy surgery followed by radiation is the recommended treatment for early-stage breast cancer; however, successful lumpectomy is contingent upon cancer-free surgical margins.
  • Current standards of intraoperative margin assessments include visual inspection, palpation, and imaging techniques, which are all less than reliable.
  • The MarginProbe® System, used during lumpectomy surgery, has been shown to reduce the need for a second surgery because of positive tumor margins.
