What is gynecomastia?
Also known as: male breast enlargement, enlarged breast in men
When infants, boys, or men have benign (non-cancerous) enlarged breasts, the condition is known as gynecomastia.
Physiologic gynecomastia commonly occurs in:
- Newborns ( ~ 90% and usually resolves in ~ 4 weeks )
- Adolescents ( ~ 50% usually around 13-14 years of age )
- Older men ( > 50 years of age )
Gynecomastia is self-limiting but can cause physical discomfort, anxiety and stress. Non-physiological gynecomastia can occur at any age and is caused by a variety of disorders and/or medications.
