Gynecomastia is excessive breast development in a male. It is generally an aesthetic problem but occasionally the breast can be painful. About 30% of males going through puberty develop mild gynecomastia. Almost always, this excessive breast tissue will subside within a couple of years. In those instances where the breast tissue does not naturally disappear or if gynecomastia appears for other reasons, surgical treatment is indicated. There are different operative approaches to the problem, depending on the type and magnitude of the breast development.
