Why does my report say “Heterogeneously Dense” tissue (Category C or D)?

Reviewed by the Medical Editorial Board on

Dense breast tissue can make a mammogram harder to read. Both dense tissue and many tumors show up as white on the scan, which can make small changes more difficult to see.

Sometimes, a doctor may suggest extra imaging, such as an MRI or Automated Breast Ultrasound, to get more information. You can talk with your doctor about whether this is right for you.
