World Dense Breast Day: What You Need to Know About Dense Breasts and Proper Support

What are Dense Breasts?

With September 25th being World Dense Breast Day, there’s no better time to discuss what it means to have “dense breast tissue.” Dense breast tissues refers to the amount of fibrous and glandular tissue in comparison to fatty tissue as seen on a mammogram. If a woman has more glandular and fibrous tissue and less fatty tissue, then she is said to have dense breasts.

In mammograms, a common finding, as nearly 40-50% of women have dense breast tissue. However, iIt’s important to know whether your breasts are dense because dense breast tissue can make it harder to detect abnormalities, like lumps or masses, on a mammogram.

So, how do you know if you have dense breasts?

Breast density is not something you can feel, so it requires medical imaging, such as a mammogram, to determine. After a mammogram, the radiologist will categorize breast density into four groups:

  • Almost entirely fatty: Low density, mostly fatty tissue.
  • Scattered areas of fibroglandular density: Some dense tissue, but mostly fat.
  • Heterogeneously dense: More areas of dense tissue, which could obscure small masses.
  • Extremely dense: Most of the breast is dense tissue, making it harder to detect abnormalities.

If your report says, "heterogeneously dense" or "extremely dense," then you have dense breasts. In most regions, if your mammogram shows dense breasts, then your healthcare provider is required by law to inform you. This will typically come as a letter after your mammogram.

It is also important to note that while breast density can't be determined by touch, there are some factors that may or may not increase your likelihood of having dense breasts including:

  • Being younger (breasts tend to become less dense with age)
  • Using hormone replacement therapy
  • Having a lower body mass index (BMI), as fatty tissue is less dense.

Why is Breast Density Important?

World Dense Breast Day is an important annual reminder to have your mammogram completed because knowing your breast density is essential for understanding your breast cancer risks. For instance, women with dense breasts have a slightly higher risk of developing breast cancer compared to women with less dense breasts. More so, dense tissue can obscure cancers on mammograms, making early detection more challenging.

For this reason, it's crucial to stay proactive about breast health, understand your mammogram results, and discuss any additional screening options with your doctor if necessary. Some women with dense breasts might be advised to consider supplemental imaging, such as ultrasound or MRI, to ensure any changes are detected early.
