New 3-D Scanning May Better Detect Breast Cancer

NPR Shots’ blog reports on a new 3-D mammogram that may help better detect early and more curable forms of breast cancer. The technique, called breast tomosynthesis, uses an X-ray machine which “swings in an arc to take about 60 1-millimeter-thick images,” as compared to conventional mammograms which take one horizontal and one vertical image of each breast. Researchers who tested the 3-D technology administered the test to 15,633 woman and found that cancer detection rates increased from 4.28 to 5.24 per 1,000 patients and that false positives decreased from 10.40% to 8.78%. Researchers warn that the 3-D mammogram is still in its early stages of testing but hope that “it’s the beginning of an evolution toward more precise, personalized breast cancer screening.”
