ABSTRACT

BACKGROUND: The female breast is a complex anatomical structure exhibiting significant morphological diversity influenced by physiological, genetic, and anthropometric variables. Despite its clinical importance in reconstructive surgery, oncology, and diagnostic imaging, standardized anatomical data defining "normal" morphological variations remain fragmented. This study aims to systematically categorize the morphological shapes of the female breast and identify the correlative anthropometric factors influencing these variations in an Indian population.

METHODS: A cross-sectional observational study was conducted on 400 healthy adult female participants. Anatomical dimensions—including chest circumference, nipple-areola complex (NAC) positioning, breast base width, and projection—were measured using standardized anthropometric protocols. Breast morphology was classified into five primary shape categories: conical, semi-conical, pendulous, discoid, and asymmetric. Correlation analysis was performed to determine the relationship between these shapes and independent variables such as Body Mass Index (BMI), age, and reproductive history.

RESULTS: The study revealed that the semi-conical shape was the most prevalent (38.5%), followed by the conical (22.0%), pendulous (18.5%), discoid (12.0%), and asymmetric (9.0%) forms. Significant correlations were observed between BMI and breast projection, with higher BMI values being positively associated with pendulous breast morphology (p < 0.05). Furthermore, age-related changes demonstrated a significant migration of the NAC inferiorly, correlating with increased glandular involution and tissue laxity. Anthropometric dimensions indicated that breast base width is a robust predictor of breast volume, independent of systemic fat distribution.

CONCLUSION: This study provides essential baseline anatomical data on female breast morphology, highlighting the influence of BMI and age on shape and projection. These findings offer clinical utility for plastic surgeons in preoperative planning and for diagnostic radiologists in identifying morphological deviations. Future research should integrate longitudinal data to further elucidate the complex interplay between genetic predisposition and soft-tissue biomechanics in breast aesthetics and functional anatomy.
