I'm 5'8", thin at 140 lbs. I had decided on 650cc. I think I should go with 600cc. I want a full D. Is 650 way too big for me?

Great question!  The difference between 600cc and 650cc isn't really that much - depending on how much breast tissue you have you're talking around 5% difference.  What is more important is how each implant matches your breast measurements, especially the base width.  If an implant is wider than your breast diameter, you definitely want to avoid that implant.  If however if they are the same width or slightly smaller, then it depends on the implant projection and how it will match with your body type.  The best way to go is to find a few breast photos you desire and present for a consultation so that a physical examination can be performed, measurements taken, and proper recommendation can be provided.  Best of luck and hope this information helps!- Dr. Roger Tsai

Hello,Stop thinking in cup sizes; that will only lead to disappointment or dismay. You would need to be seen to determine whether you have the anatomic capacity for such a large implant. If so, then you would need to be sized in front of the mirror, which is really the most important thing from your point of view; how you look, not bra cups. Go visit a few ABPS certified/ASAPS member surgeons.Best of luck!
