Breast density

What are dense breasts?

Breasts are made up of a mixture of fibrous, glandular tissue and fatty tissue. Your breasts are considered dense if you have a lot of fibrous or glandular tissue but not much fat.

Dense tissue can show up as white areas on the x-ray. Breast cancers also show up as white areas on x-rays. This makes breast cancer more difficult to detect in dense breasts.

Breasts are normally denser when you are younger and becomes less dense with increasing age. 

We recommend that you continue to have regular breast screens as the best way of monitoring for any change in breast tissue.

If you are concerned about breast density, you can call Cancer Council Victoria on 13 11 20 to talk to a cancer nurse.
