Changes to This Summary (02/06/2015)
The PDQ cancer information summaries are reviewed regularly and updated as new information becomes available. This section describes the latest changes made to this summary as of the date above.
Updated statistics with estimated new cases and deaths for 2015 (cited American Cancer Society as reference 1).
Added text to state that the net impact of screening with digital mammography versus film mammography, in terms of health outcomes and the net difference in rates of overdiagnosis, is unknown; performance of both screen-film and digital mammography for measures such as cancer detection rate, sensitivity, specificity, and positive predictive value have been compared directly in several trials, and the trials yielded similar results.
Revised text to state that among breast cancer cases diagnosed from 2004 to 2010, 62% of white women and only 52% of black women had localized disease. Also revised text to state that the 5-year relative survival rate for localized disease was 99.1% for white women and 94.0% for black women; and for distant disease, it was 26.2% for white women and 16.4% for black women (cited Howlader et al. as reference 6).
