Breast size is influenced by both genetics and the environment. Generally speaking, if the mother has larger breasts, the daughter will also tend to have larger breasts. This is because genetic genes affect breast development to a certain extent. However, genetics is not the only factor that determines breast size. Environmental factors also play an important role.

Nutritional status has a significant impact on breast development. A balanced and rich diet contributes to the fullness and roundness of breasts. In contrast, insufficient nutrition may restrict breast development. Especially during puberty, a critical developmental stage, girls' eating habits are particularly critical. Excessive dieting may lead to malnutrition, which in turn affects the intake of body fat, which may have an adverse effect on the normal development of breasts. Therefore, maintaining good eating habits is essential to promote healthy breast development.
