425cc Vs 450cc...Any Real Difference?

I do not think you will notice a “significant visible difference” between 425 mL versus 450 mL breast implants.

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.    I have found that the use of words such as “natural” or “C cup” or "heavy" 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”.

Best wishes.

 

25 cc's will not make a big difference in terms of the overall look.  Go with your cooperative decision between you and your surgeon.  Good luck.
