BackgroundWe aimed to assess factors associated with patients' confidence in the ability of screening mammography to detect breast cancer.MethodsData were analyzed from a cross-sectional, prospective survey conducted in 2017 of women without a breast cancer history who were undergoing screening mammography at our institution.ResultsIn total, 390 women completed the survey questions relevant to this study. Most respondents were 46 years or older (89.7%), White (87.6%), and college-educated (66.1%). Approximately 80% of respondents reported having confidence in the ability of screening mammography to detect breast cancer. Factors significantly associated with lower confidence in screening mammography were higher education (P = .01) and dense breast tissue (P < .001). Age (P = .12), race (P = .64), family history of breast cancer (P = .17), prior abnormal mammogram (P = .07), and mammogram frequency (P = .42) were nonsignificant. Women with a college education or higher were less likely to report confidence in routine mammography than women with less education (odds ratio [OR]= 0.43; 95% CI, 0.20-0.84; P = .02). Compared with women who reported their breast tissue as not dense, women who were aware they had increased breast density (OR = 0.16; 95% CI, 0.04-0.49; P = .004) or were unaware whether they had increased breast density (OR = 0.17; 95% CI, 0.04-0.51; P = .005) reported less confidence in screening mammography.DiscussionMost respondents were confident in the ability of screening mammography to detect breast cancer. Confidence was inversely associated with education level and self-reported increased breast density.ConclusionsThese findings highlight the importance of continued patient education about the effectiveness of screening mammography for patients with dense breast tissue.© Copyright by the American Board of Family Medicine.
