Gynecomastia: Causes, Diagnosis, Treatment and Advanced Surgical Solutions
Introduction
Gynecomastia is a benign enlargement of male breast tissue caused primarily by hormonal imbalance between estrogen and testosterone. It affects males across all age groups—newborns, adolescents, and older men—and can significantly impact confidence and quality of life.
While often mistaken for fat accumulation, true gynecomastia involves glandular or breast tissue proliferation, requiring accurate diagnosis and targeted treatment.
What is Gynecomastia? (Technical Definition)
Gynecomastia is defined as the proliferation of glandular breast tissue in males due to altered estrogen and androgen ratio.
It may present as:
- Unilateral or bilateral breast enlargement
- Palpable firm gland under the nipple
- Tenderness or sensitivity
- Psychological distress
Types of Gynecomastia
1. True Gynecomastia – Glandular tissue growth
2. Pseudo-Gynecomastia (Lipomastia) – Fat deposition without gland involvement
3. Mixed Type – Combination of fat and gland (most common)
Accurate classification is critical because treatment protocols differ significantly.
