High bone density is associated with higher endogenous estrogen levels, which are associated with a higher risk of breast cancer. Women in the highest hip bone mineral density (BMD) category are 62% more likely to develop breast cancer than are women in the lowest BMD category. Of note, women of east Asian ethnicity have lower bone density and have a lower incidence of breast cancer than white and black Americans. [35, 36, 37]
