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.
