In clinical practice in the United States, Breast Imaging Reporting and Data System (BIRADS) breast density categories are used in mammographic reports to indicate the degree of mammographic breast density a) The breasts are almost entirely fatty, b) There are scattered areas of fibroglandular density, c) The breasts are heterogeneously dense, which may obscure A woman whose breast tissue is primarily fatty replaced will have a mammogram that looks more dark There are 4 categories of breast density (also called a density score) that a radiologist uses for describing a patient's mammogram Class A (or 1) Fatty; He does so by comparing the ratio of dense tissues to nondense tissues On getting the comparison done, he assigns a report which might suggest any one of the following four levels of breast density Breast Imaging Reporting and Data System (BIRADS) is used to assign the levels of breast density These levels are named A, B, C and D

C Heterogeneously dense indicates that there are some areas of nondense tissue, but that the majority of the breast tissue is dense About 4 in 10 women have this result D Extremely dense indicates that nearly all of the breast tissue is dense About 1Four mammograms with different breast density categories are shown Breasts can be almost entirely fatty (see A), or have scattered areas of dense fibroglandular breast tissue (see B) Dense breasts are either heterogeneously dense and have many areas of glandular and connective tissue (see C), or are extremely dense (see D) The term density describes the degree of xray attenuation of breast tissue but not discrete mammographic findings c The breasts are heterogeneously dense, which may obscure small masses Some areas in the breasts are sufficiently dense to obscure small masses d The breasts are extremely dense, which lowers the sensitivity of mammography
People with heterogeneously dense breasts have more glandular and fibrous tissues and fewer fatty tissues If you have heterogeneously dense breasts, your doctor may tell you that you have fibroglandular tissue, meaning the fibrous and glandular tissues make up the largest composition of your breast40% of women fall in the category Heterogeneously Dense Breasts/Category C/5075% (considered dense breasts) 10% of women fall in the highest category 'Extremely Dense/ Category D/>75% (considered dense breasts) The higher the density, the higher the risk of breast cancer and that a tumour will be missed 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) A variation in interpretation by the radiologist can result in describing the dense/fat mixture as
The breast contains ducts, glands, fibrous connective tissue, and fatty tissue Breasts that are dense or very dense have a lot of fibrous, connective tissue and less fatty tissue Breasts that are not dense contain almost all fatty tissue and very little fibrous tissue Virtually all women start out with very dense breast tissue Over time this changes, and, as a woman ages,Level 4 breast density is the most dense breast tissue, and is composed of more than 75% glandular tissue and stroma Breast density Levels 1 and 2 are considered "nondense" due to the high proportion of fatty tissue The high proportion of fat in Levels 1 and 2 density breasts makes breast cancer detection easier because fat appears gray Fatty tissue is not muscle it's more fat Nondense means fatty tissue Heterogeneously dense has some areas of fatty tissue but most of the breast is dense Density levels are recorded in mammograms using letters AD A Almost entirely fatty meaning the breast are almost composed with fat This is usually found in 10% of women
