Estrogen plays a key role in breast changes throughout a woman’s life, according to Premier Physician Network (PPN) physicians.

During early puberty, when there is little to no estrogen, the breast tissue is dense. But as menstruation begins, estrogen levels go up and down and the breast tissue responds to the estrogen, according to PPN physicians. The hormone plays a role in the changes to the breast throughout pregnancy and breastfeeding, causing swelling and the preparation of milk production, according to PPN physicians.

As a woman goes through menopause and her estrogen levels fall, the breast tissue becomes less dense and is replaced with fat, according to PPN physicians. For more information about the role of estrogen on women’s breast changes throughout her life, talk with your doctor.
