Question: I am a 48 year old mother of three who weighs 135 pounds, and am ready to undergo breast augmentation surgery. My current size is a 36B, but I want my new breasts to be a size of DD. Which implant size will give me this result? 550cc?Answer: Determining anyone's post-operative cup size is a highly unpredictable quest. However, it is a good assumption that one cup size is equal to 100cc. Instead of using exact numbers to formulate the perfect size for you, have your surgeon customize your new size to your frame. This will allow you to go bigger, while realizing the overall change before you have the actual surgery. Good luck!
