Why Do the Same Amount of Ccs Look Different on Many Women?

This is because every woman has different body measurements. One woman may have a wider chest and smaller breast diameter, and implants of one volume will look different than another woman who has a narrower chest. I use a technique called dimensional breast augmentation which involves taking in a number of factors and measurements, so each patient is unique. That being said, given your height, weight, and your activity level, along with the fact you are considering a lift, I would say you are probably not that far off in choosing an implant in that range. Best thing to do is to see a qualified plastic surgeon that has good breast expertise.

As a part of consultation we offer the opportunity to size patients with different implant “sizers”. Many patients are surprised how different they look from their friends with implants of the same amount of ml. First of all every patients has a different amount of breast tissue to begin with. It will make a big difference if we add 400cc to A cup or a B cup. We have different body frames, some patients are tall or short, and have narrow or broad shoulders or hips. We all have different body weight. Therefore it is very important to pick that one size that fits our body type. During the consultation your surgeon will discuss if chosen implant size and type is a preferred one. There are times that the size is way too big and it is quite impossible to fit it in the chest wall. Please make sure you have the opportunity to  discuss your options.

Every woman's body type, frame, and dimensions are different. I often recommend that it is more important for patients to decide on the look you want and then discuss that with your surgeon during your in person consultation. Your surgeon will be able to help you determine which size implants will give you the results you want.

A 500 mL implant in a woman 4'11" tall weighing 100 pounds will look completely different on a woman 6 feet tall weighing hundred and 40 pounds. It is the responsibility of the surgeon to determine what volume implant will give the desired effect requested by the patient.

In order to make an accurate size recommendation, I would need to assess your chest wall and breast mound measurements and characteristics.  Unfortunately, there is not a general rule of thumb or objective criteria to implant selection.
Your plastic surgeon will perform several measurements of your chest wall and breast anatomy and determine a range of implants that both fit your chest wall and reach your desired goals.
The next step is to try on this range of implants in the office with your doctor.   The key to this success is showing your surgeon the body proportion you desire with a bra sizer and allowing your surgeon to guide you to the right implant.   It will be much easier to communicate in implant cc's than cup size when determining the appropriate implant for you.
I wish you a safe recovery and fantastic result.
