MSNBCTV NEWSA major risk of breast cancer screening may have been overestimated for decades
A new analysis suggests mammograms may lead to far less breast cancer overdiagnosis than some earlier studies indicated. Researchers reexamined all eight major randomized screening trials and accounted for differences in follow-up time, screening frequency, and screening after trials ended. Their results were consistent with an overdiagnosis rate below 5%, rather than estimates approaching 30% to 50%.
According to a new comprehensive analysis, the rate of overdiagnosis during breast cancer screening remains below 5 percent, instead of the previously believed 30-50 percent.
A new analysis of breast cancer screening suggests that the rate of overdiagnosis associated with mammograms may be less than 5%, well below the previous estimates ranging from 30% to 30%.
