Detecting breast cancer: Sonograms, 3-D mammography get closer look

New research suggests that for women with dense breasts, conventional mammography supplemented by an ultrasound scan is a costly addition unlikely to improve detection or reduce breast-cancer deaths significantly. But compared with conventional mammography alone, 3-D mammography -- also called tomosynthesis -- does increase the likelihood of detecting cancer in women with dense breasts.

The new findings emerge from two separate studies. Collectively, they suggest that for women with dense breasts -- which both raises a woman's risk of breast cancer and makes such malignancies harder to find on an imaging scan -- tomosynthesis might be a better cancer screening technique than standa...
