Dense breasts have less fatty tissue and more non-fatty tissue compared to breasts that aren't dense. Dense breasts have more gland tissue that makes and drains milk and supportive tissue also called stroma that surrounds the gland. Breast density can be inherited, so if your mother has dense breasts, it's likely you will, too.
Women whose breasts appear dense on mammograms have a higher risk for some aggressive breast cancers. One of the strongest known risk factors for breast cancer is high breast density — that is, relatively little fat in the breast and more connective and glandular tissue, as seen on a mammogram. Now, a study has found that higher breast density in postmenopausal women increases the risk of specific types of breast cancer, including some that have a relatively poorer prognosis.
Inbreast cancer became the most commonly diagnosed cancer among women in the US. After lung cancer, breast cancer is the leading cause of cancer-related mortality in women. The breast consists of several components, including milk storage glands, milk ducts made of epithelial cells, adipose tissue, and stromal tissue.

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.
A Healthy You: Prevention and Screening. Breast specialists at UW Health's Breast Center can identify dense breast tissue, which is more fibrous and thick and less fatty than non-dense breast tissue, during mammogram examination. A radiologist, who is the physician reading your mammogram, defines the amount of dense and non-dense breast tissue while examining a mammogram.
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 The intention is to make women aware of whether they have dense breast tissue so they can decide, in consultation with their health care provider, whether or not to pursue additional screening breast imaging.
Dense breast tissue is detected on a mammogram. Additional imaging tests are sometimes recommended for women with dense breasts. If a recent mammogram showed you have dense breast tissue, you may wonder what this means for your breast cancer risk.
