Breast size varies among women due to factors like genetics, hormones, body composition, and health status. Genes dictate fat storage and hormonal balance, body composition impacts fat distribution, and certain health conditions can influence these factors, causing the diversity in breast size.
Human breasts, while symbolizing femininity and motherhood, have complex structures that play pivotal roles in the body. Comprised of fatty, glandular, and connective tissues, their primary physiological function is lactation, but they also serve important sensory and cultural roles.
