Busts contains connective, glandular and fat tissues. Bust density is relative to the amount of different types of bust tissues as seen on 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.

Mammograms for dense bust may be harder to read as any abnormality such as 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 bust may be called for more follow up tests to ensure accuracy of results.
