What is dense breast tissue and how does it affect my breast health care?

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. Research has shown that dense breasts can make it harder for mammograms to detect breast cancer. Please click here for more information on dense breast tissue.
