5 Dense Breast Facts to Know:
1. Breasts are made of fat and glands that make milk, held together by fibrous tissue. The more glands and fibrous tissue compared to fatty tissue that a woman has, the “denser” her breast tissue.
2. Many women have dense breasts. This is normal and common. In fact, nearly half (over 40%) of women over age 40 have dense breasts.
3. When radiologists look at mammograms, they can see how dense the breasts are.
4. Dense tissue appears white on a mammogram, and so does cancer. This makes it harder for radiologists to see cancer in dense breasts. Because cancer can be missed, it is often found when larger and at a later stage in women with dense breasts.
5. Dense breasts are also a risk factor for breast cancer. A woman’s risk for breast cancer increases with the level of density in her breasts. ©DenseBreast-info, Inc.
