How Many CC's Should I Go with a Breast Augmentation?

You have already visualized your end result in your mind.  Your doctor should provide a way for you to visually "see" your result so that you can help determine what size implant is best for you.  Ultimately you need to be the one to choose your breast implant size, but you need to listen to the guidance of your surgeon.  Ultimately that is what you pay for is their expert guidance and counsel.

You are tall and weigh only 135, therefore your BMI is 18.8. This means you don't have a lot of fat under your skin. If you choose an implant that is wider than your breast, the border of the implant will show, because there is not enough subcutaneous tissue to create a smooth transition. In patients like yourself the breast base diameter is very important. The skin and soft tissue characteristics are also important. A silicone gel implant would be more appropriate than a saline implant when there is less tissue to cover the implant. I hope making you aware of  these general principles will help you choose the write implant size. Good luck.
