The Biology Behind Breast Size

A woman’s breast size is mainly influenced by genetics as well as hormones. Hormones such as estrogen and progesterone play an important role in breast tissue development. During puberty, rising hormone levels contribute to breast growth. Other factors—like age, weight, and lifestyle—can also impact breast size.

It’s crucial to note that having small breasts does not mean there are health problems. Every body is unique, and bust size is not a reliable indicator of overall health. Some theories reccomend that breast size may correlate with hormone production and aspects of female wellness, but this is not a rule.
