Grading Breast Density
31.12.13 / Breast Density / Author: admin
The American College of Radiology (ACR) developed a standard way of describing findings from a mammogram. It is called the Breast Imaging Reporting and Data System (BI-RADS). BI-RADS includes a category for reporting breast density.
BI-RADS 1: Less than 25% of the breast is fibrous and glandular tissue
BI-RADS 2: 25% – 50% of the breast is fibrous and glandular tissue
BI-RADS 3: 51% – 75% of the breast is fibrous and glandular tissue (this means it is now becoming more difficult to see small masses such as cysts or tumours)
BI-RADS 4: More than 75% of the breast is fibrous and glandular tissue. This is where some cancers can be missed
BI-RADS is not routinely recorded in Australia, except in Western Australia.

I have never heard of the bi-rad system used to grade breast density, only the score of the likelyhood of cancer. Now the A,b,and c I’ve heard of…but not the one two and three.
