My mammo. exam says my breast density is not dense, and there are scattered fibroglandular densities. what does this mean?

Normal variant: Young women have very dense breasts and the X ray does not penetrate well. As you age, the glandular part becomes replaced with fat which is not as dense, allowing the X ray to penetrate better. Fibroglandular densities are are areas that remain dense while the remaining breast has fat density. Usually a radiologist will carefully review mammo and possibly ultrasound. If OK just annual mammogr

Normal: The fact that your breasts are not dense makes the mammograms more reliable and the scattered densities are normal. Hope this helps.

Scattered: fibroglandular densities are not considered dense breasts. It implies that 25-50% of the breast volume is dense. ACR calls this "category B". It is just a description of the Breast density, it doesn't imply that there is an abnormality.
