Busting Dense Breast Myths

If you just got your mammogram results and saw the words "dense breast tissue," you might feel unsure what that means for you. It is normal to feel confused, worried, or anxious when you see unexpected results. Having dense breasts is common; it's not a diagnosis, and it's not something you did or didn't do. At NY Breast Health, we talk about density with patients every day and have noticed the same few myths come up repeatedly, so let's clear them up.

Breast density describes what your breast tissue is made of, not how your breasts look or feel. Breasts consist of fibrous and glandular tissue along with fatty tissue, and the ratio between them determines density. You can't tell by touch or appearance. The only way to know is through a mammogram, which is often the first time patients hear the term.

The myth we hear most is that dense breasts mean you have cancer. That's not the case. Density is normal and common. It's not a diagnosis or a sign something is wrong. About half of women who get mammograms have dense breasts. If you have dense breasts, your radiologist may recommend having a 3D mammogram or additional imaging, like an ultrasound or MRI, for a clearer picture.

Another common myth is that weight determines breast density. Someone at a higher weight can have dense breasts, and someone at a lower weight can have fatty breasts. Density is about tissue composition, shaped through factors such as genetics, age, and hormones, not by the number on a scale.

Then there's the idea that if your mom didn't have dense breasts, you won't either. Density has a genetic component, but it isn't purely inherited and can differ from one family member to the next. Your mother's mammogram results don't predict yours. The only way to know your own density is to have your own imaging done.

Knowing your breast density is useful information, not a cause for alarm. It helps you and your care team decide whether additional screening makes sense for you. Our radiologists at NY Breast Health are here to walk you through your results, answer your questions, and build a screening plan that fits your body.
