Debating the value and effectiveness of mammograms

Season 2014 Episode 430 | 9m 35s

A Canadian study conducted across more than two decades raises doubt that annual mammogram screenings reduce the risk of death among women between the ages of 40 and 59. What do the latest findings mean for women and their health? Judy Woodruff gets different viewpoints from Dr. Carol Lee of the Memorial Sloan Kettering Cancer Center and Dr. H. Gilbert Welch of the Dartmouth Institute.
