I had silicone implants (textured bag)placed ,back in 1991. That was the 2nd time after first ones had problems. So they have been in now for 21 years. I’ve had no problems with them , but have just been told I need to replace them before they rupture. As at some point they probably will. It is not a procedure that I want to do again , after having them done twice to begin. I am now 54 and was hoping they would be fine indefinitely . Do you think the procedure needs to be redone ? If so why? If not why not?
