There are scattered areas of dense glandular tissue and fibrous connective tissue (together known as fibroglandular density) The breasts are heterogeneously dense, which means they have more of these areas of fibroglandular density. This may make it hard to . Dense breast tissue refers to the appearance of breast tissue on a mammogram. It's a normal and common finding. Breast tissue is composed of milk glands, milk ducts and supportive tissue (dense breast tissue), and fatty tissue (nondense breast tissue). When viewed on a mammogram, women with dense breasts have more dense tissue than fatty tissue. The breast is normally composed of fat and glandular tissue – the higher the proportion of glandular tissue, the denser the breast. The denser your breast tissue, the more “white” the breast will appear on a mammogram; women with primarily fatty breasts will have a mammogram that appears darker.
The breast is normally composed of fat and glandular tissue — the higher the proportion of glandular tissue, the denser the breast. Digital mammograms are better than older film screen mammograms for evaluating dense breast tissue, and the newer 3D tomosynthesis mammograms provide additional clarity. However, all mammograms are limited in their ability to mammograms and glandular breast tissue
through dense tissue and identify cancers, as cancers usually appear as white lumps on a mammogram. It was previously thought that mammograms simply had a harder time detecting breast cancer in women with dense breast tissue. However, it appears that women with mammograms and glandular breast tissue
breast tissue have an increased risk for developing breast cancer.
