“…Similar to Kerlikowske et al, we observed relatively low false‐positive risks in Asian women. Studies from the Carolina Mammography Registry, which is part of the BCSC, reported that compared with white women, black women had similar specificity on screening mammography but lower specificity on diagnostic mammography and hence more false‐positive biopsy recommendations . These observations are consistent with our findings of a similar cumulative risk of false‐positive recall yet a higher cumulative risk of false‐positive biopsy recommendation in black women compared with white women.…”

Background Biennial screening mammography retains most benefits of annual breast cancer screening with reduced harms. Whether screening guidelines based on race/ethnicity and age would be more effective than age-based guidelines is unknown. Methods Mammography data from the Breast Cancer Surveillance Consortium were linked to pathology and tumor databases. We identified 40-74 year-old women who had annual, biennial, or triennial screening mammography during 1994-2008. We used logistic regression to estimate adjusted odds ratios (OR) and 95% confidence intervals (CI) of adverse tumor characteristics among 14,396 incident breast cancer cases and 10-year cumulative risks of false positive recall and biopsy recommendation among 1,276,312 noncases. Results We found no increased risk of adverse tumor characteristics associated with biennial versus annual screening in white women, black women, 40-49 year-old Hispanic women, or 50-74 year-old Asian women. Hispanic women aged 50-74 who screened biennially versus annually had increased risk of late stage (OR 1.6, 95% CI 1.0-2.5) and large (OR 1.6, 95% CI 1.1-2.4) tumors. Asian women aged 40-49 who screened biennially had elevated risk of positive lymph nodes (OR 3.1, 95% CI 1.3-7.1). No elevated risks were associated with triennial versus biennial screening. Cumulative false-positive risks decreased markedly with longer screening interval. Conclusion We found limited evidence of elevated risk of adverse tumor characteristics with biennial versus annual screening, while cumulative false-positive risks were lower. However, elevated risks of late stage disease in Hispanic women and node-positive disease in younger Asian women who screened less often than annually warrant consideration and replication.

Background: Many jurisdictions have used public funding of health care to reduce or remove price at the point of delivery of services. Whilst this reduces an important barrier to accessing care, it does nothing to discriminate between groups considered to have greater or fewer needs. In this paper, we consider whether active targeted recruitment, in addition to offering a 'free' service, is associated with a reduction in social inequalities in self-reported utilization of the breast screening services in NSW, Australia.

“…(34) However, among the same population the specificity of diagnostic mammography, that is, mammograms performed after an abnormal screening exam or symptoms, was 25% lower for black women compared to whites. (35) Similarly, a study of the Breast Cancer Surveillance Consortium found overall callback rates for blacks and whites were comparable, but there was a higher probability of false-positive biopsy recommendations for blacks compared to whites. (36) Of note, the vast majority of screening exams in both of these cohorts were film rather than digital mammograms, and these studies controlled for first mammogram, but not use of comparison films at interpretation.…”

Background Mammography screening reduces breast cancer mortality, but false-positive tests are common. Few studies have assessed racial differences in false-positive rates. Objectives We compared false-positive mammography rates for black and white women, and the effect of patient and facility characteristics on false-positives. Research Design and Subjects Prospective cohort study. From a sample of the American College of Radiology Imaging Network (ACRIN) Digital Mammographic Imaging Screening Trial (DMIST), we identified black/African American (N=3176) or white (N=26,446) women with no prior breast surgery or breast cancer. Measures Race, demographics, and breast cancer risk factors were self-reported. Results of initial digital and film mammograms were assessed. False-positives were defined as a positive mammogram (Breast Imaging Reporting and Data System [BIRADS] category 0, 4, 5) with no cancer diagnosis within 15 months. Results The false-positive rate for digital mammograms was 9.2% for black women compared to 7.8% for white women (p=0.009). After adjusting for age, black women had 17% increased odds of false-positive digital mammogram compared to whites (OR=1.17, 95% CI 1.01-1.35, p=0.033). This association was attenuated after adjusting for patient factors, prior films and study site (OR=1.04, 95% CI 0.91-1.20, p=0.561). There was no difference in the occurrence of false-positives by race for film mammography. Conclusion Black women had higher frequency of false-positive digital mammograms explained by lack of prior films and study site.The variation in the disparity between the established technique (film) and the new technology (digital) raises the possibility that racial differences in screening quality may be greatest for new technologies.
