New study says 3-D mammograms could be better at detecting cancer
CHICAGO - According to a study published in the Journal of the American Medical Association on Tuesday, 3-D mammograms may be better at finding cancer than regular scans, but it isn't known if that means saving more lives.
Nearly half a million breast scans were involved in the study. Over one-third used relatively new 3-D imaging in combination with conventional scans. The rest used regular mammograms alone.
One additional cancer per 1,000 scans was detected with the 3-D combo, compared with conventional mammograms. There were also 15 percent fewer false alarms.
However, the study wasn't designed to determine whether the combined 3- scans resulted in better long-term outcomes. Still, researchers say their results are promising.
