There are several things to consider in large volume breast augmentation. The largest size implant that will fit depends on base width diameter of your breast but also on the distance from your nipple to breast fold and the amount of loose skin that is available to stretch. Large breast implants, especially greater than 500cc can be heavy and are more prone to sagging over time. Placing the implants under the muscle is important because there is an additional layer of support to counteract gravity. With large breast implants, it is even more important to wear a bra all day. Before you make a decision about large volume breast augmentation you may need more than one opinion. Beware of surgeons who say that you can have any size implant that you want. It's not that simple.
