3D mammography finds more invasive cancers, reduces recalls
SIOUX FALLS, S.D. – Three-dimensional mammography finds significantly more invasive cancers and reduces unnecessary recalls, according to a large, retrospective study published in the Journal of the American Medical Association (JAMA) featuring data from Edith Sanford Breast Center.
The study, “Breast cancer screening using tomosynthesis in combination with digital mammography,” was led by Sarah Friedewald, M.D., of Advocate Lutheran Hospital in Park Ridge, Illinois, and co-authored by Thomas Cink, M.D., a breast radiologist for Sanford Health in Sioux Falls. It focused on the impact of 3D mammography at a diverse range of sites across the United States. The study looked at nearly half a million mammograms, including 30,000 from Sanford Health.
Results indicated that 3D mammography lead to a 41 percent increase in invasive cancer detected, a 15 percent decrease in unnecessary recalls for false alarms and a 29 percent increase in the detection of all breast cancers.
“Three-dimensional mammography finds more of the invasive, harmful cancers and saves women the anxiety and cost of having additional screenings for what turns out to be a false alarm,” said Cink. “Women see little difference between a conventional 2D mammogram and a 3D mammogram; the exam takes just a few seconds longer and the positioning is the same, but I believe the real difference is in the enhanced information available to the doctor with a 3D image.”
Edith Sanford Breast Center in Sioux Falls has utilized 3D screening technology since 2012. The program’s radiologists are fellowship trained in breast imaging.
The study was published online in advance of its appearance in a future print issue of JAMA.
