Gynecomastia is a condition in which the male's breast tissue enlarges. This increase in tissue usually occurs at times when the male is having hormonal changes, such as during infancy, adolescence, and old age.
This is usually a benign (noncancerous) condition that may be caused by many different hormonal changes, or, in some cases, the cause may be unknown. The changes in hormones usually include an increase in estrogens or a decrease in androgens (testosterone). Sometimes, this condition may be associated with other diseases that must be ruled out in order to make a diagnosis. In some conditions, including breast cancer, liver diseases, lung cancer, testicular cancer, tumors of the adrenal glands or pituitary gland, drug use, certain congenital (present at birth) syndromes, or thyroid disorders or trauma, gynecomastia presents itself as a symptom.

Your surgeon will help decide if you are a candidate for surgery.
The type of anesthesia used will depend on many factors, including your preference, the surgeon, the extent of the growth, your age, and the size of the incision. Either local with intravenous sedation or general anesthesia may be used. The surgeon often will make marks on the skin before surgery to indicate the areas to be removed.
