A study and editorial in today's New England Journal of Medicine continues the debate over the value of mammograms. The study, conducted in Norway and at Harvard University, centered on women in their 40s, when breast cancer is relatively rare but aggressive. It concludes that screening doesn't save many lives, even among women aged 50 to 69, who are at higher risk of the malignancy.
