There is great variation among women in the density of breast parenchyma as seen on mammograms. Mammographic density also varies inversely with age. Thus, younger women tend to have denser breasts than older women, but many older women also have dense breasts.

The mammographic density of breast parenchyma depends on the amount of connective tissue and glandular tissue in the breast. Breasts dominated by adipose tissue, which appear less dense, are easy to assess with mammography.
