Women with dense breast tissue have a higher risk of breast cancer than women with fatty breast tissue. C: Heterogeneously dense indicates that there are some areas of nondense tissue, but that the majority of the breast tissue is dense. 40% have scattered fibroglandular densities. The calcium readily absorbs the X-rays from mammograms. Dense breast tissue contains a higher percentage of glandular and fibrous tissue than fatty breasts, which makes it more difficult for tumors to be detected during a mammography.
