Breast density is a measure used to describe mammogram images. Breasts are made up of breast tissue the milk ducts and lobules, which may be called glandular tissue and fat. Connective tissue helps hold everything place.
The idea was originally met with scepticism, but consensus now is that it is indeed a true risk element and of interest to screening mammography. Essentially, breast density is a comparison of the relative amounts of fat versus fibroglandular tissues in the breast. Fibroglandular parenchyma, basically means breast tissue.
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.
Breasts contain glandular, connective, and fat tissue. Breast density is a term that describes the relative amount of these different types of breast tissue as seen on a mammogram. Dense breasts have relatively high amounts of glandular tissue and fibrous connective tissue and relatively low amounts of fatty breast tissue. Only a mammogram can show if a woman has dense breasts.
Caroline Ho, MD. The Federal Drug Administration FDA has proposed a change that requires mammography facilities to include information about breast density in letters to patients regarding their annual mammogram. Although this is a change on a national level, Minnesota has been required to share this information with patients since
Breast density varies considerably among women, and can also change over the lifespan as a woman ages. For this reason, physicians should inform women undergoing mammograms of their personal level of breast density. Breast density refers to the relative proportion of the three main contents of the breast: 1 milk-producing glandular tissue and ducts, 2 stroma—the internal scaffolding of the breast that holds everything in place, and 3 fat tissue which serves as a filler to keep the breast soft and pliable.

Breast density is a strong, prevalent, and potentially modifiable risk factor for breast cancer, which makes it of special interest to clinicians whose jobs involve breast cancer risk prediction. Kerlikowske delivered the John I. Mammographic breast density is a radiologic term, Dr.
Some mammogram reports sent to women mention breast density. Your health care provider can also tell you if your mammogram shows that you have dense breasts. In some states, women whose mammograms show heterogenously dense or extremely dense breasts must be told that they have dense breasts in the summary of the mammogram report that is sent to patients sometimes called the lay summary.
