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.
Breast cancer is the second leading cause of cancer death in women. Although mammography is well known to be a powerful screening tool in the detection of early breast cancer, it is imperfect, particularly for women with dense breasts. In women with dense breast tissue, the sensitivity of mammography is reduced.
Women with low breast density have more fatty tissue compared to glandular tissue while women with high breast density have more glandular tissue compared to fatty tissue. Breast density describes how breasts look on a mammogram. It does not describe how breasts feel on examination by a woman or their doctor.
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.
The primary dataset will not be shared because it is subject to confidentiality restrictions. Breast density is known to affect breast cancer risk and screening sensitivity, but it may also be associated with breast cancer survival. The interpretation of results from previous studies on breast density and survival is complicated by the association between detection mode and survival.
Most of the material in Ellen DeGeneres' Netflix special, Relatableis about how America's favorite happy-go-lucky daytime TV host is both filthy rich and mind-bogglingly famous, yet still very much a human being. For decades, mammograms have been a largely unchanging fact of life for American women. But last week, for the first time in 20 years, the FDA issued a list of proposed changes to its mammography guidelines focusing on a breast cancer risk factor that, until now, many women may never have considered: Whether we have high or low density breasts.
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.
Breasts are made up of several different components that include fat, glandular tissue the milk ducts and lobules and connective tissue, which helps hold everything in place. High breast density means there is a greater amount of glandular and connective tissue compared to fat. Low breast density means there is a greater amount of fat compared to glandular and connective tissue. Glandular and connective tissue shows up white on a mammogram, fat shows up dark on a mammogram.
