What Is Gynecomastia?
Gynecomastia is a medical condition characterized by the development of excess breast tissue in men. It may affect one or both sides of the chest and can occur at any age, from adolescence through adulthood. Gynecomastia is most commonly caused by a hormonal imbalance between estrogen and testosterone, but it may also be influenced by genetics, medications, weight changes, or underlying medical conditions.
Unlike excess chest fat alone (sometimes called pseudogynecomastia), true gynecomastia involves firm glandular breast tissue. Understanding the stages of gynecomastia can help patients better recognize their condition and explore appropriate treatment options.
How Is Gynecomastia Classified?
Physicians often classify gynecomastia into stages or grades based on:
- The amount of glandular breast tissue
- The presence of excess fat
- Skin elasticity and laxity
- Overall chest contour
At Modern Surgical Arts of Denver, Dr. Kamran Dastoury uses this staging approach during consultation to determine the most effective and individualized treatment plan.
Stage One Gynecomastia
Stage One gynecomastia is the mildest form of the condition. It typically involves:
- A small amount of firm glandular tissue beneath the nipple
- Minimal to no excess skin
- Subtle chest fullness that may not be visible under clothing
In some cases, especially during puberty, stage one gynecomastia may improve on its own. Treatment may include monitoring, lifestyle modifications, or addressing hormonal factors. Gynecomastia surgery may be considered if the tissue persists, causes discomfort, or affects confidence.
Stage Two Gynecomastia
Early Stage Two Gynecomastia
Early stage two gynecomastia involves:
- Moderate enlargement of glandular breast tissue
- Firm skin without significant laxity
- Increased visibility through fitted clothing
At this stage, non-surgical management may still be considered in select cases, but persistent glandular tissue often responds best to surgical correction.
Later Stage Two Gynecomastia
Later stage two gynecomastia includes:
- More pronounced breast tissue growth
- Mild skin laxity
- A rounded or fuller chest appearance
As the condition progresses, gynecomastia surgery in Denver is often recommended to remove glandular tissue and restore a flatter, more masculine chest contour.
Stage Three Gynecomastia
Stage Three gynecomastia is the most advanced form and typically involves:
- Significant breast enlargement
- Excess skin
- Visible sagging or drooping of the chest
At this stage, surgical treatment is usually the most effective option. Surgery may involve removing excess glandular tissue and fat, along with skin tightening or skin excision, to achieve a more natural and masculine chest appearance.
