Do breasts get firm when they're growing?

Yes, breasts can become firmer during periods of growth, such as puberty or hormonal changes. This firmness is often due to the development of glandular tissue and increased fat deposits in the breast. Additionally, hormonal fluctuations, particularly increases in estrogen, can lead to temporary swelling and firmness. However, breast firmness can vary widely among individuals and may change over time due to factors like age, weight, and hormonal levels.
