What Size is 550cc?

There isn't an exact correlation between an implant size and final breast size.  The amount of breast tissue and breast size preop is one of the key issues.  If you have a small amount of breast tissue, a 550 cc implant would be more noticeable of a change.  Larger breasts and frame can tolerated a larger implant with only moderate change in cup size.  You will need a physical examination to determine which is more likely.   I would advise against being too focused on cup size as that is very fungible.  Cup size varies by bra company and measurement methodology.  It is more helpful to show your surgeon what you feel is a natural and ideal outcome with photos.  Trying implants under a bra can also help, but is less exacting.   It sound like you need to have more of a discussion about breast size with your surgeon.  Good luck!

Thank you for the question.

There is no absolute correlation between breast implant size and cup size. Be careful that you do not base your communication of goals and/or satisfaction with the outcome of breast surgery on achieving a specific cup size. As you know, bra cup sizes vary from one bra manufacturer to another.

 In my practice, I encourage patients to use goal pictures to communicate their goals;  I asked them to show us pictures of what they would like to achieve as well as pictures of breasts that are too big or too small…

 Also, since you mentioned that you have gained weight, it is best that you achieve a long-term stable weight prior to undergoing any type of breast surgery.

 I hope this helps.
