However, since no breast prostheses have been implanted for a full life span, it is impossible to give an unequivocal statement in this regard. It is important to emphasize that this is an estimate, and future data may lead to a better knowledge of the overall long-term risk of leakage. As is the case in all surgery, there are certain risks that are inherent in this operation. Although the scars are usually well hidden, irregularity or thickening of scars can occur which might require revision. Rarely, hemorrhage may require removal of prosthesis to control the bleeding.
Infection is probably the most serious risk of breast augmentation.
If an infection occurs, antibiotics alone will rarely clear up the infection unless the implant is removed. It is necessary to leave the implant out for a period of about three months before it is safe to attempt replacement. While it is usually confined to the early post op period, infection from mycobacteria can occur much later. Another potentially serious complication is implant rejection. Silicone is the least reactive material used for implant construction.
