Male breast formation or Gynaecomastia is not uncommon in young men. It can be associated with puberty, weight gain or as a side effect of certain drugs. Investigation often turns up nothing and the condition is then called idiopathic.
Treatment involves a subcutaneous mastectomy via a small areolar incision combined with liposuction of the chest wall. A drain is often left in temporarily and a chest compression garment is put on. The surgery is performed under a GA and an overnight stay is unusual.
Resumption of normal activities is possible within a week.
