How common are complications due to having implants?

There are many complications that can occur with breast augmentations with capsular contracture being the most common. Nation wide Capsular contracture occurs in about 9% of augmentations over the life of the implant. There many things that can be done to help prevent capsular contracture that are patient and surgeon dependent. Ultimately your question about the frequency of complications needs to be directed to your surgeon as we each have our own rate of complications. For example I almost never see bottoming out but my technique is very different than your planned surgery.

The modern day generation silicone gel implants are one of the safest medical devices in the history of medicine. There is extensive high level evidence from experts in breast implant surgery showing the safety of these devices over the last 30 years. I would go see a board-certified plastic surgeon (with plastic surgery residency and aesthetic fellowship training) for a consultation.

Dear shayyyymw,
there have been numerous studies on the safety and efficacy of silicone breast implants. The FDA has approved them to be safe and breast augmentation is the most common cosmetic surgical procedure performed in the United States every year. Implants are much different than they used to be with rigorous testing and cohesive gel. I can't tell you how happy my breast augmentation patients have been with their implants.
I would recommend a consult with a plastic surgeon to go over all of your concerns. Saline implants are also a perfectly good option if you are still concerned and are less expensive.
