What Are Breasts Made Of? Fat Or Breast Tissue?

Posting Date: 04/01/1999

Email Question From Ray: My wife and I have a bet about breasts - she says they're made of fatty tissue and I say they're made of breast tissue.

Dr. Dean: Both of you are right.

Breasts contain both fatty and breast tissue.

Breast tissue is glandular.

Women with larger breasts - for example, a C or D cup - have a higher volume of fatty tissue in their breasts.

When women breastfeed, their breasts change and increase the percentage of breast tissue.
