In the June 25, 2014 issue of the Journal of the American Medical Association (JAMA), a groundbreaking study was published that found 3-D mammography (also called breast tomosynthesis) screening technology significantly increased cancer detection while simultaneously reducing the number of false positives.
The study, “Breast Cancer Screening Using Tomosynthesis in Combination with Digital Mammography,” reviewed close to half a million mammography exams, and was led by Sarah M. Friedewald, MD of the Caldwell Breast Center, Advocate Lutheran General Hospital in Park Ridge, Illinois.1
Researchers found that 3-D mammography finds significantly more invasive/lethal cancers than a traditional 2-D mammogram. According to the study’s results, 3-D mammography also reduces the number of women called back for unnecessary screenings due to false alarms, thereby reducing anxiety AND health care costs.
Other significant findings include:
- A 41% increase in the detection of invasive breast cancers
- A 29% increase in the detection of all breast cancers
- A 15% decrease in women recalled for additional imaging
- A 49% increase in Positive Predictive Value (PPV) for a recall
- A 21% increase in PPV for biopsy
- No significant change in the detection of ductal carcinoma in situ (DCIS)
This study used Hologic 3-D mammography systems and involved 13 U.S. breast screening sites and 139 radiologists.
The Breast Center at St. David’s Medical Center is committed to early identification and the fight against breast cancer. The Breast Center provides 3-D mammography, the latest in breast screening technology. If you would like to schedule a mammogram, or if you have questions about this important breast health procedure, please call 512.544.8800.
