The enlarged breast in men is called gynocomasta. The doctors are not very shure why it happens, but imbalance in the testosterone level can be one reason others can be drug abuse etc. The only solution is Surgery. General surgeon can perform the surgery under local anesthesia[ means injecting the chest are with a numming agent] and you will be released out in the same day. Liposuction is another good solution where the surgeon will pull out the fats form the breast using a surgical needle with a pipe attached to a pump and you will be released in a few hours after dressing. You have to be lying flat on the bed for one week wearing a belt and then after opening the stitches you will be asked to not pull weight for a month or so after that you will leave a normal life. But before surgery get in touch with doctors of the ENDOCRINOLOGY department will ask you to preform some blood tests and some scans to identify the cause of your problem- I AM A FORMER GYNACOMASTIYA PATIENT
