What is the difference between a 200g silicon implant and 200cc?

Thank you for your question. There is essentially no difference between the two as 1 cm³ of silicone breast implant weighs approximately 1 g. Hope that clarifies it for you

There is no difference at all. The two modes of measurements are almost the same and you could use either. However, in the clinic, cc is usually the unit used for the implants.
