Thanks for your question.Looking at your photos, from what I can tell you have some ptosis (lower positioning of the nipple) and some stretch marks (tears) of your skin. 650cc implants will fill up that space and add lots of volume for you.Here are somethings I would consider:1) 650cc implants are very heavy, almost 1 1/2 pound of weight per breast. With somewhat damaged skin and low nipples I believe there is a possibility of implant migration downwards, and over time, bottoming out.2) The base of these implants are wide and may not match the base width of your breast, as a result these implants can migrate down and out for both breasts.3) Your breasts have different shapes, sizes and chest wall positions. These implants will take what is present and making them look bigger and possibly more different.4) With the added 3 pounds (approximately) of weight to your chest any exercise, running, sleeping could be problematic. In addition, your back, your neck and your shoulders may suffer. I say this only in that patients with naturally large breasts, who present for reductions have these issues and can't wait to making the size smaller.5) Considering all the above I believe you are at increased risk for more breast surgeries down the road.6) You are a small person and 650cc implants will look very, very large on you. If that is the look you desire then you are right on. If you want a look that is full and more proportional with lifting of your nipples, you may need another type procedure called a mastopexy with augmentation.7) I strongly suggest that you seek the advice of a surgeon who is Board Certified by the American Board of Plastic Surgery. There are many specialties performing breast surgery; not all of them are real Plastic Surgeons.I hope this helped.Stephen M. Davis, MD, FACS
