40cc difference between my left and right size. Is it normal to increase the difference if I was only 30cc before?

Dear LoTay11,
I understand your concern. However, without a proper assessment, it would be difficult to determine what went wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

Implants only come in certain size intervals. At the size you chose they often go in larger intervals than with smaller sizes. That’s probably why your surgeon used those sizes.,there was no 30. Cc difference they were able to use.

I would suggest discussing this with your surgeon. He/she may have felt that this would be more even while you were on the table.

Dear LoTay11,
I will stick with my last answer. Let's start with "your breasts look great." The rest you have already read on your last question.

You are noticing the difference in either size or shape due to the revision. A 10cc change is almost imperceivable.
