Breast growth in men can be caused by some medicines, diseases, or body-building hormones. Apart from these, natural physiologic breast growth is also possible, as the case is in infancy and puberty. The growth of breasts in men is called gynecomastia. During the gynecomastia surgery, the excessive breast tissue is removed. Optionally, liposuction may be added to the operation. Gynecomastia surgeries are simple and do not leave any scar.
