Comparative StudyMammographic breast density and subsequent risk of breast cancer in postmenopausal women according to tumor characteristics.
Few studies that investigated the associations between breast density and subsequent breast cancer according to tumor characteristics have produced inconclusive findings. We aimed to determine whether the associations between breast density and subsequent breast cancer varied by tumor characteristics. ⋯ The findings suggest that higher mammographic density is associated with more aggressive tumor characteristics and also with in situ tumors.
