Breast Cancer Detection Rate Improves with New Screening Technique

Adding a 3D imaging technique called tomosynthesis to digital mammography appears to result in both a reduction in the number of patients being called back for additional testing and an increase in breast cancer detection rates. Digital tomosynthesis takes multiple X-ray pictures from different angles. The breast is positioned as it is for a conventional mammogram, but less pressure is applied. Instead of a single image with conventional mammograms, this technique offers a 3D image for a better evaluation of the breast. Dr. Sarah M. Friedewald writes, “The association with fewer unnecessary tests and biopsies, with a simultaneous increase in cancer detection rates, would support the potential benefits of tomosynthesis as a tool for screening. However, assessment for a benefit in clinical outcomes is needed.”
