Having to undergo a second lumpectomy - something that happens in 20 percent of lumpectomy cases - adds to a patient's mental strain, according to breast surgeon Dr. Beth-Ann Lesnikoski, medical director of the Breast Institute at JFK Medical Center in Atlantis.
"The additional surgery is very minor, but it's an additional surgery.
And it's more time the patient feels that she
might have cancer in her
began using the device a month ago and has used it during 10 lumpectomies.
The device's analysis of a tumor's edges (or margins) is complete in about five minutes.
When an alert indicates cancer may be present at a tumor's edges, the surgeon will, most often, remove more tissue at the corresponding spot in the body, according to Lesnikoski
That prevents the need for a second surgery in many cases, she
The surgeon said she
has ignored the device's alert only once, because she
knew from years of experience that a particular mass highlighted by the device was not cancer.
"very impressed" with the device.
Using radio waves, the device scans removed breast tissue from all angles to determine whether cancer remains at any of its margins, Lesnikoski
The waves pass through normal breast tissue at a different rate than they do cancerous tissue, she
The diagnostic imaging device, approved by the FDA in 2013, produces a different sound when cancer is detected than it does when tissue margins appear free of cancer, she said.
MarginProbe also activates a blue light for a negative (clear) reading and a red light for a positive one.
"If it comes back positive, the circulating nurse can make a notation that very precisely tells you where to take more tissue," Lesnikoski
Younger women and women on hormone replacement therapy tend to have denser tissue, Lesnikoski
physician said women in those categories should consider whole-breast ultrasound, magnetic resonance imaging or molecular breast imaging (which use a radioactive tracer) when scheduling screenings.
Effective screening is critical to reducing deaths caused by breast cancer, she
With most women, the standard mammogram - a low-dose X-ray scan - can identify tumors too small to detect by hand, as well as tiny deposits of calcium that could signal the presence of cancer.
The United States Preventive Task Force recommends
that women ages 50 to 74 get a mammogram every two years.
Women with a family history of breast cancer might want to consider starting mammograms earlier.
"It's not perfect, but it's the best tool we have," Lesnikoski
