Will 650cc Breast Implants Drop and Have Cleavage?

If you go forward with your plan of getting 650 cc implants, I'm afraid people will stop making eye contact with you - they'll be too busy staring at your large chest!
650 cc implants have very little chance of looking natural. Given their size relative to your small frame, they have the possibility of dropping too much and violating the natural crease at the base of the breast. This can be a very difficult problem to fix down the road. They will also stretch out your breast tissue and skin considerably.

Before you get these implants put in, make sure you have a long discussion with your surgeon about the potential long-term ramifications of such large implants. Also make sure that your surgeon is certified by the American Board of Plastic Surgery.

Best of luck. Hope this helps.

Eventhough I dont know your size and weight and height, I would say 650 cc breast implants are very big implants. They will drop over time but your chances of capsular contracture is higher. What I recommend you do is the rice test which will help you determine what size implant you would go for and the look you are going for. I have explained this on my website journal page.
Good luck.
