Why don't they fill those implants with silicone that is semi-gelled? Instead of using that liquid goo. That way, if and when the implant ruptures, the silicone that escapes is gelatinous and removable, instead of a fluid that escapes into the body.
For that matter, why don't they fill the implant with "nodes" of gel silicone, mimicing the actual physical make-up of breast tissue (milk ducts)?
Now, where's my giant novelty-sized paycheck from Dow Corning?
