Study Questions Value of Mammograms, Breast Cancer Screening
A new study questions the value of mammograms for breast cancer screening. It concludes that a woman is more likely to be diagnosed with a small tumor that is not destined to grow than she is to have a true problem spotted early.
Mammograms do catch some deadly cancers and save lives. But they also find many early cancers that are not destined to grow or spread and become a health threat. There is no good way to tell which ones will, so many women get treatments they don't really need. It's a twin problem: overdiagnosis and overtreatment.
