CHICAGO (AP) — 3-D mammograms may be better at finding cancer than regular scans, a large study suggests, although whether that means saving more lives isn’t known.
The study involved almost half a million breast scans, with more than one-third of them using relatively new 3-D imaging along with conventional scans. The rest used regular mammograms alone.
The 3-D scan combo detected one additional cancer per 1,000 scans, compared with conventional digital mammograms. There were also 15 percent fewer false alarms — meaning fewer initially suspicious scan Login to read more
