WEDNESDAY, June 11 (HealthDay News) -- The accuracy of mammography screening is affected by certain characteristics of the facility where it's performed, a U.S. study finds.

Researchers looked at data from 44 sites that performed 484,463 screening mammograms on 237,669 women between 1992 and 2002.

Of those women, 2,686 were diagnosed with breast cancer. On average, breast cancer was identified when it was present (sensitivity) in 79.6 percent of breast cancer cases that occurred within one year. Mammograms were correctly identified as cancer-free (specificity) 90.2 percent of the time.
