In late October 2009, the U.S. Preventive Services Task Force (USPSTF), an independent panel of primary care experts, was preparing to release their updated guidelines for the use of screening mammograms, which were given to women in an attempt to detect evidence of breast cancer at a treatable stage. The new guidelines, based on rigorous scientific research and tests, now recommended routine screening starting at age 50 rather than at age 40. The challenge the USPSTF faced was that this shift in the recommended starting age was likely to spark significant debate among medical professionals and in the press. Also available is the supplement 9B14M021.
