How Many Cc is Needed for 36 to 38C Breasts?

Sandra,
Breast implants come in many shapes and sizes. For a given implant volume, the projection can be normal, moderate or high. It all depends on the shape of the shell and design of the implant. So, you need to look at more than just cc when deciding on an implant.
The considerations you need to include are your breast base diameter, remaining tissue & desired final size. If you have already had the mastectomy, then you may also need an breast expander placed first to help stretch the skin to the desired size. After several months, this can be replaced with the final implant. During the expansion process you can get an idea of what volume you like, since they will be expanding your implant on a weekly or biweekly basis. I hope this is helpful and good luck with your reconstruction.

I have spent alot to time answering this question and it is extremely common but there is no easy answer and it really depends on several factors but primarily your body and the bra design. The size of the implant is the last and most important determinant
YOUR BODY
Your amount of breast tissue, your weight , thickness of subcutaneous tissue, chest circumference, etc
BRA DESIGN
This actually prompted me to research the project and eventually design a product for which I recieved a US patent.
One of the issues is that bra makers/designers tend to deviate from standards. It is kind of similar (reportedly) to fashion designers labeling their clothes with a smaller size than it truly is (a size 4 dress is marked as a size 2 dress) just to make the customer feel better.
The confusion is compounded by the design of the cup. I recently looked at a Victoria Secret's catalog and was surgprised that one bra came in:

Unlined
Lightly lined
Pushup (no Padding)
Padded

Level 1
Level 2
Level 3
Level 4
Level 5



IMPLANT SIZE:
There are many sizing methods including such techniques as the zip lock filled water bags, water filled condoms, rice filled nylons, and silicone sizers.
One device currently available is the B4Bra (b4bra.com) which also uses sizers that are disposable.
Place any of these sizers in a sheer bra and determine what size (in cc) you prefer and relate this to your surgeon.
The difficult problem will be accounting for and compensating for the volume of the removed breast tissue.
In general, it takes about 325-375cc to take the average A cup to a C cup. However, this is only a gross estimate.
