Breast augmentation (boob job) is done to enlarge small breasts and to provide an aesthetic appearance. The general anesthesia method is preferred for surgery. The operation usually takes 1-2 hours. A breast prosthesis (breast silicone, breast implants, or gummy bear implants) is used to enlarge the breast. The fat injection technique is also used to enlarge the breasts. However, it is not as successful as the technique in which breast implants are used.
