Is 425cc implant to big?

I prefer not to go quite that large when combining a lift with implants.  It depends on how much of your own breast tissue you have and photos would help. But if you are already a C cup, 425 cc's added to that will be quite large.

The choice of an implant size depends on many factors
including: your anatomy, desired appearance, realistic expectations, chest
width, existing breast tissue dimensions, and extent of laxity of the
skin and underlying tissues. The best cosmetic results are not just dependent
on the number of CCs, but also on proper width, height, and projection of the
implant for your particular anatomy, since every patient is different.Following the advice of anyone on this or any other
website who would presume to tell you what to do without taking a
full medical history, examining you, feeling and assessing your tissue tone,
discussing your desired outcome and fully informing you about the pros and cons
of each option would not be in your best interest. Find a plastic surgeon that
you are comfortable with and one that you trust and listen to his or her
advice. The surgeon should be certified by the American Board of Plastic
Surgery and ideally a member of the American Society for Aesthetic Plastic
Surgery (ASAPS). You should discuss your concerns with that surgeon in person,
and try on sizers.Robert Singer, MD FACSLa Jolla, California
