In pre-menopausal women the opposite was the case: although there was no correlation between age and breast density, higher vitamin D levels tended to be associated with lower breast density (p = 0.06 for ACR 2 vs. ACR 4) in this smaller sample (n = 412). The higher the breast density level the more intense the "blizzard" is. . In pre-menopausal women the opposite was the case: although there was no correlation between age and breast density, higher vitamin D levels tended to be associated with lower breast density (p = 0.06 for ACR 2 vs. ACR 4) in this smaller sample (n = 412). A radiologist uses a mammogram to determine the ratio of fatty to dense tissue in your breasts, ultimately assigning you one of the below levels of breast density: Type A ("Fatty") Composed almost entirely of fatty tissue.

The risk for breast cancer is twice as high in women with category D breast density as it is in women with breast density between categories B and C; women with category C breast density have only a slightly increased risk. We examined the relationship between MD and serum 25-hydroxyvitamin D [25(OH)D], an integrated measure of vitamin D . Adding Mammographic Density to Standard Measures. This is because breast cancers are more difficult to see on mammography in women with increased breast density.

Category B: There are scattered areas of dense glandular and fibrous tissue (seen as white areas on the mammogram). Dense breast tissue makes it harder to find cancer in the breast. Normal dense breast tissue looks white on a mammogram, and so do tumours. The breasts are almost entirely fatty (about 10% of women).

What is density in the breast and what do the 4 categorgies of breast density levels mean? A new study looked at a 10-minute "abbreviated MRI," or AB-MRI, to determine whether it might be more effective (and affordable) than 3D mammography for women with dense breasts.
