Does Bust Density Matter?

Updated: Nov 8, 2022


Bust, Density, mammogram, check

Busts contain connective, glandular and fat tissues. Bust density is relative to the amount of different types of bust tissues as seen on a mammogram. A dense bust would mean that there is a higher amount of connective and glandular tissue as compared to fat tissue in the bust. To know if you have a dense bust, you’ll have to go through a mammogram as the density of a bust cannot be felt through a bust self-exam or a clinical bust exam.

There are 4 categories to bust density.

1. Fatty

This category refers to busts that are almost entirely made of fatty tissue. Around 10% of women are in this category.


2. Scattered

This category refers to a bust that has scattered areas of dense glandular and connective tissue. Around 40% of women are in this category.

3. Heterogeneously Dense

This category refers to a bust that has many areas of glandular and connective tissue. Around 40% of women are in this category.


4. Extremely Dense

This category refers to a bust that is extremely dense. Around 10% of women are in this category.


A dense bust may refer to category 3 or 4.

Mammograms for dense busts may be harder to read as any abnormality such as a tumour or cancer in the bust will appear as white on a mammogram. This means that it may be camouflaged or very hard to be seen on the mammogram. Women with dense busts may be called for more follow-up tests to ensure the accuracy of results.
