How does a girls bubes grow?

Breast development in girls begins during puberty, typically between ages 8 and 13, as a result of hormonal changes, particularly increased levels of estrogen. The growth occurs in stages, starting with the formation of breast buds, followed by an increase in fatty tissue and glandular tissue. Genetics, body weight, and overall health also play significant roles in breast size and growth. This process can continue into the late teens or early twenties as the body matures.
