I have 450cc implants. I'm wanting to go to 550cc. Should I? (Photo)

It is not that big of a difference, but if you want to go bigger you certainly can.  You might also look at the extra high profile.  I don't know if you have preop Vectra photos, but that is helpful as you can still simulate the other sizes.  Good Luck!

Thank you for the question. Keep in mind as you are thinking about your goals that sometimes adjustment of the breast implant pockets (capsule adjustments) may be necessary to achieve the outcome you are looking for. Also keep in mind that there is no accurate/reliable/predictable correlation between size/profile breast implant utilized and cup size achieved.  

Generally speaking, the best online advice I can give to ladies who are considering revisionary breast augmentation surgery is:

1. Concentrate on choosing your plastic surgeon carefully. Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. Ask to see lots of examples of his/her work.
2. Have a full discussion and communication regarding your desired goals with your plastic surgeon. This communication will be critical in determining breast implant size/type/profile will most likely help achieve your goals.
In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. I have found that the use of words such as “natural” or "up a cup size” or "DD cup" etc means different things to different people and therefore prove unhelpful.
Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup size may also be inaccurate.
3. Once you feel you have communicated your goals clearly, allow your chosen plastic surgeon to work with you in determining the best plan to achieve your goals.

I hope this, and the attached link (dedicated to revisionary breast augmentation surgery concerns), helps. Best wishes.
