Background Groups of immigrant and minority women are more often diagnosed with advanced stage breast cancer than other women. Mammographic screening aims to reduce mortality from breast cancer through early detection in asymptomatic women. Purpose To compare mammographic screening attendance among immigrant and minority women to that of other women. Material and Methods A literature search of PubMed, Embase, Google Scholar, and Cochrane identified 1369 papers published between January 1995 and March 2016. In the review, we included 33 studies investigating mammographic screening attendance among immigrant and/or minority women. In a meta-analysis, we included 19 of the studies that compared attendance among immigrant and/or minority women with that among other women, using a random effects model. Results The review included studies from Europe, North America, and Oceania, with 42,666,093 observations of opportunities for mammographic screening. Attendance was generally lower among immigrant and minority women compared to other women (46.2% vs. 55.0%; odds ratio = 0.64, 95% confidence interval = 0.56–0.73; P < 0.05, I2 = 99.9%). Non-Western immigrants had lower attendance rates than other immigrants. Conclusion Immigrant and minority women had lower mammographic screening attendance than other women, which could potentially put them at increased risk for more advanced breast cancer. This review emphasizes the importance of continued efforts to engage with the preventative health needs of diverse populations in attempts to achieve equality in access to, and use of, care.
