The breast surgeons at Torrance Memorial’s Hunt Cancer Institute
are committed to using the latest technology to provide patients with
the most advanced breast cancer care. As part of that commitment, our
surgeons use a device called the MarginProbe® to determine whether
the breast tissue surrounding the site of the removed tumor is cancer-free.
The MarginProbe® Procedure
The breast surgeons at Torrance Memorial use the MarginProbe® during
lumpectomy procedures to test the edges, or margins, of the removed breast
tissue. The system can detect the presence of ductal carcinoma in situ
(DCIS) and invasive breast cancer.
The MarginProbe® provides real-time, detailed information about whether
the edges of the excised tissue contain cancer cells. With results available
in minutes, the surgeon can decide immediately whether to remove additional
tissue from the tumor site before completing the lumpectomy procedure.
Detecting the presence of cancer cells during surgery reduces the likelihood
that the patient will have to undergo a second surgery to remove additional
How MarginProbe® Works
The MarginProbe® System uses electromagnetic waves to identify potentially
cancerous tissue. It does this by assessing the electromagnetic response
of the removed breast tissue, giving it an electromagnetic “signature,”
and comparing that signature to the signatures of healthy and cancerous
tissues contained in its database.
The Benefits of MarginProbe
The MarginProbe® was approved by the U.S. Food and Drug Administration
(FDA) in 2013. According to research associated with the FDA approval,
women whose surgeons used MarginProbe® were 56 percent less likely
to need a second surgery than women whose surgeons did not use MarginProbe®.
In addition to having a higher likelihood of cancer-free, or “clean,”
margins after surgery, patients whose surgeons use MarginProbe® don’t
have to wait several days for the pathology report, which lessens their
anxiety after surgery.

Meet Our Surgeon
As a breast cancer survivor, Torrance Memorial breast surgeon, Dr. Melanie
Friedlander, is personally committed to providing the most up-to-date
care for her patients. As part of that commitment, Dr. Friedlander uses
MarginProbe® technology during her lumpectomy procedures. This innovative
system allows her to quickly determine if cancer cells are present around
the edges of the tumor site, reducing the risk that her patients will
require a second breast surgery.
