Breast Density Matters

What is Breast Density?

Breast density refers to the amount of normal, non-fatty tissue visible in a woman’s breasts. Dense breast tissue is comprised of less fat and more fibrous and connective tissue. This tissue appears white on a mammogram. Unfortunately, so does cancer; making it difficult to detect a cancer. Radiologists can only determine breast density through mammography.

Breast Density Categories

A – The breasts are almost entirely fatty.

B – There are scattered areas of fibroglandular density.

C – The breasts are heterogeneously dense, which may obscure small masses.

D – The breasts are extremely dense, which lowers the sensitivity of mammography.

What To Do If You Have Dense Breasts

• Conduct monthly breast self-exams.

• Schedule an annual mammogram.

• Obtain a copy of your mammogram report and carefully read the description of your breast density.

• Ask your doctor about your risk factors and potential need for additional screening (ultrasound, breast MRI, etc.).
