A number of studies conclude that breast cancer screening has little to no effect on mortality. Is it time to scrap the practice?
A study published last month in the New England Journal of Medicine once again called in to question the utility of screening mammograms. Although this study was an observational one, a number of randomized trials have been done in countries including Norway, Sweden and the Netherlands, as well as a systematic review of the data, all of which conclude that population-based breast cancer screening has little to no effect on mortality.
In a New York Times article, David H. Newman, MD, asserts that “doctors and patients continue to ignore the science on mammograms.” Do you agree?
