- Abstract
Objective: The present study aimed to evaluate the benefits of breast ultrasonography in addition to mammography in routine breast cancer screening, stratified by breast density. Method: 49 middle-aged Bangkokian women were recruited by convenient sampling. All participants had undergone both mammography and ultrasonography. BI-RADS categories were assigned based on mammography results alone and combined mammography and ultrasonography results. Concordance rates between the two radiographic techniques were compared in women classified based on their breast densities. Results: Discordance rates of BI-RADS scores between mammography versus adjunctive ultrasonography was highest in extremely dense breasts (60%), followed by heterogeneous dense breasts (50%). Heterogeneous fibroglandular breast density was the most common breast density in our study, which presented with less than 35% discordance between the two imaging modalities. Conclusion: The use of adjunct ultrasonography had the most significant benefit in women with dense breasts, as reflected in a higher BI-RADS score detected. Results from our study suggests that a differentiation of breast cancer screening practice should be based on breast density. Women with extremely dense breasts should be screened by both mammography and ultrasonography, while women with less dense breasts may be evaluated by mammography alone.
