I have been looking for some time for a plastic surgeon a little closer to Norway so I dont have to go that incredibly far. I have now found one but when I asked if i would have to replace the implants, I got the answer that they must be replaced at least every 15 years. I started to look online and it says that you usually never have to change them unless you get an infection or that the implant is damaged. So now im not sure if this is a good place and do you have to get it changed that often?
