The Impact of Tuberous Breast on Adolescents: A Cross-sectional Study

Tuberous breast deformity is a nondiagnostic, descriptive term for a congenital breast difference that becomes apparent at puberty. Although the negative physical and psychosocial effects of macromastia and breast asymmetry are established, no studies to date have explored the impact of tuberous breasts on health-related quality of life (HRQoL) outcomes using a robust sample size.

In this cross-sectional study, HRQoL surveys were administered to adolescent women with tuberous breasts and healthy female controls, aged 12-21 years. Surveys included the Short-Form 36v2, Rosenberg Self-Esteem Scale, and Eating Attitudes Test-26. Demographics were compared, and linear regressions were fit to determine the effect of tuberous breast deformity on survey scores, with body mass index (BMI) category as a covariate.

Thirty-four patients with tuberous breasts and 264 controls participated. Patients with tuberous breasts had higher mean BMI than controls (P < 0.05). After adjusting for differences in BMI category, patients with tuberous breasts scored lower than controls on the Rosenberg Self-Esteem Scale and in Short-Form 36v2 domains related to physical and psychological health (P < 0.05, all). Compared with controls, patients with tuberous breasts had a higher mean score on the Eating Attitudes Test-26 (P < 0.05).

Tuberous breast deformity may negatively impact patients' physical and psychosocial HRQoL and increase their risk for disordered eating and higher BMIs. It is imperative that healthcare providers and third-party payors understand tuberous breast deformity is not just a cosmetic issue and tailor care and coverage policies accordingly.
