Gynecomastia is a benign medical condition of enlarged glandular tissue of the male breast. There are a variety of factors that can lead to this condition, but the most commonly it is an unknown cause. A surgery can be performed to excise (remove) the glandular tissue through a half circle incision along the areola edge. This incision will disguise well along the areola when the scar fully matures. After the excision of this tissue it will not come back. However, if one gains excessive weight the fat cells of the breast/chest may increase in size. If this occurs, the fat cells may be removed via liposuction, which can be combined with traditional gynecomastia surgery if desired. In conclusion, the excision (removal) of the breast glandular tissue will not come back or regenerate after the gynecomastia procedure and provides a smoother chest contour.
