Why Different Ccs? Is there much difference in getting 25 less ccs in one breast and the other with 25 ccs more?

Almost every woman has one breast that is slightly bigger or smaller than the other. Sometimes this is a very notable difference and sometimes it is minute. 25 cc is a small amount, but often just enough to balance the chest wall on a patient that has a slight volume asymmetry.

Small differences in cc's in breast implants are common to achieve a perfect result. In a large breast, 25 cc's  may be hard to tell much of a difference. Let your PS decide which size is best for you. 

Thanks for your question. I know that it seems very small since it is less than one ounce. No one however has mirror image breasts. About 20% of the breast augmentations I do require different implant sizes to correct an asymmetry. The tricky part is if there is a very large volume difference because as implants get larger, they get wider. If your plastic surgeon feels it is necessary, you can either trust them or seek a 2nd opinion. Best of Luck!
