When males have a prominent breast, it is called Gynecomastia. Often young boys with this condition are embarrassed to go swimming, go to the beach, or take their shirt off in the locker room. The condition usually affects both sides, but can be only on one side.
Surgery to correct this is very effective, and can involve a combination of liposuction and excision of the excess tissue. Most patients wear a compression vest for a few weeks after the surgery to minimize swelling, and there is very little downtime.
