That trade-off is a key question as doctors begin recruiting 165,000 women nationally to compare potentially more beneficial 3-D mammograms — known scientifically as "tomosynthesis" — with standard two-dimensional digital mammography. The 3-D mammograms have been marketed as being able to find more cancers. And the U.S. Preventive Services Task Force, a government advisory group, recommends starting at age 50, with mammograms every other year. WHAT ABOUT 3-D MAMMOGRAMS? Breast cancer is far less common at age 40 than at age 50 and beyond.
