Gynecomastia is a common condition where breast tissue grows in boys or men, causing breast enlargement. It can be caused by an imbalance of hormones during puberty, certain medications, or other factors. Surgery is the most effective treatment for gynecomastia and involves removing the excess breast tissue to restore a natural, masculine chest contour.
