Breast augmentation  is a medical operation belonging to the field of reconstructive and aesthetic surgery. It can occur for both aesthetic reasons and medical reasons (for example, the breast is not properly formed or needs to be reconstructed after amputation). It’s most commonly done with implants, but there’s also an option using fat transfer. Implants: These are silicone or saline-filled shells inserted under the breast tissue or chest muscle. They come in various shapes, sizes, and textures to achieve different looks. Fat transfer: Liposuction removes fat from another area of your body, which is then processed and injected into the breasts for fullness.
