Abstract

Gynecomastia is a benign enlargement of the male breast tissue, either due to the proliferation of glandular tissue or deposition of fat in breast tissue, usually caused by imbalance of estrogen and androgen hormones in body. Gynecomastia has a trimodal age distribution and begins as a small lump beneath the nipple which may be tender. Gynecomastia is usually benign but may be a cause of embarrassment for some. Evaluation of gynecomastia is performed with an aim at diagnosing the cause for the same. Individual treatment requirements can range from simple reassurance to medical treatment or even surgery depending on the etiology.
