Just found this….
REJECTION is an immune mediated response in which our body recognizes something as foreign and then mounts an attack to remove it.
Breast implants (either saline or silicone filled) are made of a silicone shell which in thousands of studies has been shown NOT to elicit an immunological rejection response. NO implant in the history of human existence has been more intensely studies than breast implants; it has been more studied than heart valves, pacemakers, artificial vessels, joints and all other implants.
Like all operations breast augmentation does have some risks associated with it, but rejection is NOT one of them.
Hope that helps hun xxx
