Not all male breast enlargement is due to gynecomastia. When the enlargement is caused by fat deposits rather than breast tissue growth, it is known as pseudo-gynecomastia. To determine the cause of the enlargement, Dr. LaBarbera will perform diagnostic tests. If the condition is due to excess fat, a proper diet and exercise regimen may be suggested as the initial treatment. If these measures do not resolve the issue, liposuction may be considered as a corrective procedure.
