Dr. Steven Quay What is dense breast tissue? How is breast density determined?
Dense breast tissue refers to the appearance of breast tissue on a mammogram. It’s a normal and frequent finding.
Breast tissue is composed of glands that make milk during breast feeding, ducts that conduct milk to the nipple, and supportive tissue (dense breast tissue), and fatty tissue (nondense breast tissue).
Dense breast tissue is whiter on a mammogram which makes it difficult to see through. Fatty tissue is grayer on a mammogram.
When viewed on a mammogram, women with dense breasts have more dense tissue than fatty tissue.
