Study revives argument over mammogram screening

Yearly mammograms starting at age 40 would prevent the most deaths from breast cancer, U.S. researchers reported on Monday in a challenge to more conservative recommendations that take into account both the harms and the benefits of screening. The study, led by Dr. Elizabeth Arleo, a radiologist specializing in mammography at Weill Cornell Medicine and New York-Presbyterian, found that yearly mammograms between the age of 40 and 80 could cut breast cancer deaths by 40 percent.
