Study finds mammograms reduce cancer deaths
Health Key

The longest study yet to examine women who undergo mammography shows that it reduces deaths from breast cancer by at least 30%, a finding that many doctors say may help ease the recent controversy surrounding the procedure.

The three-decade study in Sweden showed that one breast cancer death can be prevented for every 414 to 519 women who are screened, a much lower number than the 1,000 to 1,500 that had been projected in previous studies.
