2014-07-11 Notice in the left example the composition is c - heterogeneously dense, although the volume of fibroglandular tissue is less than 50%. The fibroglandular tissue in the upper part is sufficiently dense to obscure small masses. So it is called c, because small masses can be obscured. Historically this would have been called an ACR 2: 25-50% density.

Knowing whether you have dense breasts is important because women with dense breasts have a higher risk of developing breast cancer, and often need supplemental screenings to a mammogram. Our Dense Breasts Q&A Guide answers these commonly asked questions: Some people have more fibrous than fatty tissue in the breasts. This can increase their risk of breast cancer and make it harder to diagnose. Learn more about dense breast tissue here. Women with dense breasts have been shown to have a four- to six-fold increased risk of developing breast cancer; only age and BRCA1 and BRCA2 mutations increase risk more. Breast density is a radiologic phenomenon different from the common notion of density as weight per unit of volume.

The breast tissue is heterogeneously dense, which could obscure detection of small masses (approximately 51% - 75% glandular) 4. The patient below has “heterogeneously dense” breast tissue, which means that more than half of the tissue in her breast is dense.

When comparing women who have extremely dense breasts to women who have fatty replaced breasts, the risk of developing breast cancer in women with dense breasts is increased by 4 to 6 times. Often, if a woman has heterogeneously dense or extremely dense breasts, the reporting radiologist will recommend supplemental screening with breast ultrasound.

A radiologist evaluates the mixture of dense and fatty tissue to determine your breast density and categorizes it into one of four categories fatty, scattered fibroglandular density, heterogeneously dense, or extremely dense (see Figure 1). NCI's Dictionary of Cancer Terms provides easy-to-understand definitions for words and phrases related to cancer and medicine. C. HETEROGENEOUSLY DENSE – There are large portions of the breast where dense (fibroglandular) tissue could hide masses. Such breasts are considered “dense.” About 40% of all women have heterogeneously dense breasts.
