The answer is this You are right, 400 cc implants on a woman with considerable breast tissue will make her breasts bigger than the same implant in a woman with no breast tissueBut - the 400 cc implant will stick out on the chest of a small-chest woman and look proportionally much...
Your surgeon needs to advise you as to the implants that will fit your chest.You appear to have a wide chest and want a dramatic look. Generally in that case, although larger implants tend to cause more problems over time, you will be happier with the 550 cc implant. Best wishes.
Thank you for the question and congratulations on many years of enjoying the outcome of breast augmentation surgery! There is no way of predicting exactly how long your saline breast implants will be problem free. Also, there is no time limit as to when or if you need to exchange...
