Characterizing the association between breast density and risk of tumor subtypes may enhance our understanding of how breast cancer subtypes differ in etiology. The goal of this study was to use 3D MR-based density method to investigate the association of breast density with the development of different subtypes of breast cancer. In total 114 women diagnosed with unilateral breast cancer were analyzed. A negative correlation between age and percent breast density was noted, with older women tended to have lower density. ER negative and triple negative cancer had higher PD than other tumor subtypes, but no statistical difference was identified.
