Will I Fin 475cc's/515cc's too Big?

Thank you for your question.  If your breast width diameter is 11.5 - 12.  the 475 cc are probably too big.  a 475cc high profile implant has a base width of 13cm.  If it is too wide, the implants pushes out too far laterally against your arm.  The only way to know for sure is to have a direct physical examination so we can get accurate measuremnts.

Based only on your breast base width, 475cc to 515cc implants are likely to be too big for your chest and result in a less than ideal outcome.

It's difficult to make an assessment without a photo but I would point out that going to the size you are suggesting may be too large for your chest diameter, I would also have a concern about potential sagging after such large implants because you are more likely to bottom out at that size.

Thank you for the question.

Unfortunately, it is not possible to give you good advice without direct examination and discussion of your goals.

In planning your breast augmentation revision surgeryIn planning your breast augmentation procedure it will be very important to communicate your size goals with your surgeon.  in my practice I find the use of goal pictures to be very helpful.  in your case you could use your own before breast-feeding pictures as the goal. I have found that the use of words such as “natural” or “C cup” or "fake looking" or "top heavy" 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.

I use  intraoperative sizers and place the patient in the upright position to evaluate breast size. Use of these sizers also allow me to select the breast implant profile (low, moderate, moderate plus, high-profile) that would most likely achieve the patient's goals. The patient's goal pictures are hanging on the wall, and allow for direct comparison.
I have found that this system is very helpful in improving the chances of achieving the patient's goals as consistently as possible. 
By the way, the most common regret after this operation, is “I wish I was bigger”.

I hope this helps.

It is difficult to say soley from you height and weight if 475-515 cc sized implants will be appropriate for your situation.  Remember you final size will be the size of the implants PLUS the volume of your normal breast.  Also, remember that the implants will be a part of you 24/7.   You may be concentrating on a low cut gown on a date night - remember the implants will also be there when you are exercizing or in a more conservative setting such as a business meeting.  Good luck on your decision.
