The size of breasts if someone were a woman depends on many factors including genetics, body weight, hormone levels, and overall health. Breast size varies widely among women and is influenced by inherited traits from family, body fat distribution, and hormonal influences such as estrogen. If you want a more personalized estimate, sharing information such as your current body frame, weight, and family history of breast size could help. Otherwise, breast size predictions are generally uncertain without specific biological factors. Would you like information on the main factors that determine breast size or how hormone therapy and other factors affect breast development?
