Dense breast tissue on mammogram

Breast density on mammogram is reported as one of four categories.

• breast tissue primarily fatty

• scattered fibroglandular tissue

• heterogeneously dense tissue

• extremely dense tissue

After a routine screening mammogram, about 50% of women receive results indicating they have either heterogeneously dense or extremely dense breast tissue. These women are advised to discuss with their health care provider the option of having a screening ultrasound.
