A new study which uses modeling to summarize the benefits and harms of breast cancer screening finds that regular mammography screening for women ages 50 to 74 reduces the risk of dying due to breast cancer, with a smaller benefit for women 40 to 49. False-positives tests and overdiagnosis are of concern for all ages, although false positives are more common for women in their forties, and over-diagnosis is more of a concern for older women.
