Additional mammogram readers improve breast cancer detection
... Studies have shown that breast cancer detection may increase when mammograms are reviewed by both a radiologist and a mammographic technologist. In The Netherlands, a breast cancer screening program was implemented in the 1990s that required all mammograms be read by two radiologists. Mammographic tec...Other highlights in the July 24 JNCI
