Last November, a government task force sparked a fiery debate when they questioned whether starting mammograms at age 40 saves lives. They suggested moving the recommended age up to 50.
A study out Wednesday doesn't address age, but the researchers found mammograms save two lives for every one who is given unnecessary treatment.
The recommendation still stands that women should start getting mammograms at age 40.
It is recommended even earlier, if they have a family history.
