Dear Fahmi,
Thank you for your post. Nationally, this is the 'biggest' question that women have after augmentation and the most common reason for revision. For this reason, I usually push women to go slightly larger than they were originally thinking. The largest size possible for a given patient depends on skin and tissue strength, and chest dimensions and cannot accurately be given without all of these issues. In general, though, I choose my implant sizes based on chest dimensions, base diameter of the breasts and desired cup size, rather than cc's. However, for comparison, the following link is a petite girl with relatively narrow chest who is 5'6" and had 500 cc high profile implants placed.
Best Wishes,
Pablo Prichard, MD
