Breast augmentation and breast implants are related terms, but they refer to slightly different things.    Breast augmentation is a surgical procedure that is designed to enhance the size, shape, or symmetry of a woman's breasts. This procedure may involve the use of breast implants, but it can also involve other techniques, such as fat transfer.    Breast implants, on the other hand, refer specifically to the medical devices that are used to augment the breasts. Breast implants are typically made of silicone or saline and are inserted into the breasts during surgery to increase their volume and enhance their shape.    In summary, breast augmentation is a general term that refers to any surgical procedure that is used to enhance the appearance of the breasts, while breast implants specifically refer to the medical devices that are used to achieve this result. Breast augmentation may or may not involve the use of breast implants.
