Compliance with screening mammography and breast sonography of young Asian women

ObjectiveWe evaluated compliance with mammography and breast sonography and the factors related to compliance.Study designFrom August 2005 through July 2006, 1239 asymptomatic women, aged 40–49 years, were enrolled in the study. Compliance in the second year was calculated. Telephone interviews examined the impact of the women's experience during mammography or sonography on adherence to rescreening.ResultsThe rates of compliance with mammography and sonography for breast cancer screening were 73.5% and 80.1%, respectively (p = 0.006). More women receiving mammography (12.2%) reported unsatisfactory results (BI-RADS category 0) than those undergoing sonography (6.2%) (p < 0.001). During the telephone interview, 74.9% of the women complained of pain during mammography, but none (0%) during sonography (p < 0.001); 69.8% felt embarrassed during mammography and 55.6% during sonography (p < 0.001). Multivariate logistic regression analysis showed that pain (OR 0.096, 95% CI 0.044–0.213) and unsatisfactory examination results (BI-RADS category 0) (OR 0.042, 95% CI 0.020–0.090) were barriers to not following up mammography. Embarrassment (OR 0.645, 95% CI 0.419–0.994) and unsatisfactory examination results (OR 0.169, 95% CI 0.085–0.336) were barriers to not following up sonography.ConclusionsFor young Asian women with dense breast tissue, compliance with sonography for breast cancer screening was better than that with mammography.
