heterogeneously dense
A breast tissue composition category indicating scattered fibroglandular densities that may obscure small masses on mammography.
Full Definition
One of four standardized breast density categories used in mammographic interpretation, indicating that the breasts contain scattered areas of fibroglandular density. This density classification suggests that small masses might be obscured by the overlying tissue, potentially reducing mammographic sensitivity. Women with heterogeneously dense breast tissue may benefit from supplemental screening methods such as breast ultrasound or MRI. This density category affects both cancer detection rates and legal notification requirements in many jurisdictions, making accurate classification important for appropriate follow-up recommendations.
Usage
Usage note: Hyphenate when used as a compound modifier; follows BI-RADS density classification system.
