Breast implants can be positioned above or underneath the pectoralis major muscle, the incision can be placed along the areola, underneath the breast, or in the armpit. And different materials (saline or silicone) can be used inside the implant. With more implants always coming into the marketplace, there is no substitute for experience in your doctor. When patients, from around the world, ask me about breast augmentation, my best advice is to know and trust your doctor and to make sure your idea of beauty aligns with theirs. Look at their results. If they don’t show you their results, or if they only show a few results, this could be a red flag.
