With saline mentor implants you can go as high as 960 cc but it requires a wide width base of the breast to accomodate such implant. There are various risks involved with placement of a large implant. Good luck.
The largest implants made by the manufacturers available in Canada (Mentor and Allergan) are around 800cc. With a Mentor Becker implant, you can go as high as approximately 1000cc. Having said that, the complication rate and risk of revision surgery increases with implant size once you go above approximately 350cc.I hope that helps answer your question.
