Every element and structure on earth has some component of “leakage”; but the word itself when used in relation to breast implants has taken on the meaning of not just weeping outside its original confines but actually traveling distances to other parts of the body. This simply does not happen.
The implants have a “gummy bear” silicone consistancy within a silicone shell. Even when the integrity of the shell is compromised, the gel stays intact and physically does not travel outside the biologic capsule made by our body to isolate the implant. Silicone (gel) implants have been shown to be safe and have no causal relationship to cancer or connective tissue disease.
