Can Dense Breasts Increase Breast Cancer Risk?

Did you know that you should consider the density of your breasts? It can affect your breast cancer risk factor and determine what type of mammogram you should get. 

Breast density isn’t something you can control and it often changes over time. It is unrelated to how your breasts feel or seem. It has to do with how they look on a mammogram.  

If you have dense breasts, you will be told by the doctor or technician during your mammogram. The law in many parts of the U.S. requires radiologists to inform you if you fall into that category. Having dense breasts is a normal and very common condition. However, you may not know exactly what it means or what to do. Here are answers to some general questions about dense breasts you may have. 

Can Dense Breasts Increase Breast Cancer Risk? 

What are dense breasts? 

Breast tissue comprises glandular, connective, and fatty components. The density of breast tissue on a mammogram analyzes how much of each type of tissue is present. Compared to fatty breast tissue, dense breasts possess relatively high amounts of glandular tissue and fibrous connective tissue.  

How do I know if my breasts are dense? 

If a woman has dense breasts, only mammography can reveal this. Both a clinical breast exam and a breast self-exam cannot detect dense breast tissue. Because of this, dense breasts are also known as mammographically dense breasts. 

What factors contribute to dense breasts? 

Age and genes are the primary factors. Breast tissue tends to be denser in younger women who have higher estrogen levels in their bodies. Additionally, you are more likely to have dense breast tissue if your mother did. Body weight or build has no influence on having dense breasts. There is a decrease in breast density after menopause as estrogen levels decrease.
