With Routine Mammograms, Some Breast Cancers May Be Overtreated

The endless debate over routine mammograms is getting another kick from an analysis that sharply questions whether the test really does what it’s supposed to.

Dr. H. Gilbert Welch, coauthor of the analysis of mammography’s impact, which was just published in The New England Journal of Medicine, tell Shots that the aim was to “get down to a very basic question.”

That is, do annual mammograms among women over 40 discover early-stage breast cancers that can be treated so that they never become deadlier late-stage tumors?
