Definition of Gynecomastia
Breast enlargement in a man. Gynecomastia may be a symptom of obesity or hormonal imbalance such as may occur during puberty or with various endocrine disorders that affect the production of testosterone.
Estrogen levels in the blood circulation tend to rise with chronic liver disease or damage to the liver. Gynecomastia is also a characteristic side effect of hormone therapy to treat prostate cancer, again because the balance of estrogen in the blood circulation increases.
Treatment depends on the underlying cause.
See also MASTALGIA.
