Is 650cc Silicone too Big For My Frame? 5'8, 133 lbs, have 390cc Now.

Some women want large breasts and that is their business.  The plastic surgeon's responsibility is to make sure the new implants do violate the anatomic borders of the breast.  When implants are quite large, silicone gel is usually a preferable choice.

Without examining you it is difficult to be sure, but if you have 390cc now, then going to 650+/- should be ok. Silicone is better choice for larger implants.

Good luck.

It would be impossible for anyone to say whether 650cc would be too big for your frame based on the information that you provided. Going from 390cc to 650ccs  is a 40% increase in breast implant volume which will clearly make for a visible size difference. If going with silicone, be certain that you are getting high profile implants so they do not end up going too far to the side. 

Without an exam it is hard to say what would be best for you.  With revision, and going to a mcuh larger implalnt may increase your risk of early problems.

Without a physical exam, it is impossible to give you perfect advice, just guidelines.  The weight of your 390 cc saline, is about 410 grams (as they don't weigh the shell of the implant with the size).  So you are going roughly a cup and a half bigger (I use 150cc per cup size as a rule of thumb).  I do that frequently in my practice, but not without significant counseling before hand.  It sounds like more than most women think that it is after they are in.  This is a common size change in my practice in southern California.  Good luck.
