BACKGROUND The cumulative risk of a false positive result from a breast-cancer screening test is unknown. METHODS We performed a 10-year retrospective cohort study of breast-cancer screening and diagnostic evaluations among 2400 women who were 40 to 69 years old at study entry. Mammograms or clinical breast examinations that were interpreted as(More)
BACKGROUND Computer-aided detection identifies suspicious findings on mammograms to assist radiologists. Since the Food and Drug Administration approved the technology in 1998, it has been disseminated into practice, but its effect on the accuracy of interpretation is unclear. METHODS We determined the association between the use of computer-aided(More)
BACKGROUND The U.S. population of former prison inmates is large and growing. The period immediately after release may be challenging for former inmates and may involve substantial health risks. We studied the risk of death among former inmates soon after their release from Washington State prisons. METHODS We conducted a retrospective cohort study of all(More)
PURPOSE We investigated the efficacy of contralateral prophylactic mastectomy (CPM) in reducing contralateral breast cancer incidence and breast cancer mortality among women who have already been diagnosed with breast cancer. METHODS This retrospective cohort study comprised approximately 50,000 women who were diagnosed with unilateral breast cancer(More)
BACKGROUND Radiologists differ in their ability to interpret screening mammograms accurately. We investigated the relationship of radiologist characteristics to actual performance from 1996 to 2001. METHODS Screening mammograms (n = 469,512) interpreted by 124 radiologists were linked to cancer outcome data. The radiologists completed a survey that(More)
CONTEXT Breast cancer screening in community practices may be different from that in randomized controlled trials. New screening modalities are becoming available. OBJECTIVES To review breast cancer screening, especially in the community and to examine evidence about new screening modalities. DATA SOURCES AND STUDY SELECTION English-language articles of(More)
BACKGROUND Previous studies have shown that the agreement among radiologists interpreting a test set of mammograms is relatively low. However, data available from real-world settings are sparse. We studied mammographic examination interpretations by radiologists practicing in a community setting and evaluated whether the variability in false-positive rates(More)
Because of recent studies showing strong prevention benefit and acceptable psychosocial outcomes, more women may be considering prophylactic mastectomy. A growing literature shows some positive psychosocial outcomes for women with bilateral prophylactic mastectomy, but less is known about women with contralateral prophylactic mastectomy. Several surveys(More)
