scattered fibroglandular breast tissue
(SKA-terd FY-broh-GLAN-juh-ler brest TIH-shoo)
A term used to describe breast tissue that is made up of mostly fatty tissue and also has some dense fibrous tissue and glandular tissue. On a mammogram, the dense areas of the breast make it harder to find tumors or other changes. Scattered fibroglandular breast tissue is one of four categories used to describe a level of breast density seen on a mammogram. About 40% of women have this type of breast tissue.
