Surgical Gel Used To Stop Bleeding Could Confuse Mammograms

MAYWOOD, Ill. -- Dr. Kathleen Ward noticed something odd when she examined the mammogram of a patient who had recently undergone breast cancer surgery.

The Loyola University Health System radiologist saw a suspicious pattern of white specks, much like grains of salt. The specks were calcium deposits similar to microcalcifications that sometimes are a sign of early breast cancer. But it was too early for the patient's breast cancer to have returned because it had been only a month since her lumpectomy.

It turns out the microcalcifications were not from cancer. Rather, they were due to a gel that is sometimes used during surgery to stop bleeding. In a recent article in the American Journal of Roentgenology, Ward and colleagues reported seven cases in which the sealant mimicked malignant microcalcifications in mammograms.

The sealant, FloSeal, "is not recommended for use on breast tissue," Ward and colleagues wrote. Ward is Medical Director of Women's Health Imaging and an assistant professor in the Department of Radiology at Loyola University Chicago Stritch School of Medicine.
