I visited 2 doctors, one prefer to use medpor material, because I have a thin skin, and medpor is not moving. But he was warning me, it can get infected after years, and silicon is that same. But I've read on the internet, that medpor is commonly getting infected because of the pore structure. The second doctor have different opinion, and he thinks that, if medpor once enter the body, there's less possibility to get infected, than with silicone implants. What do you think about it?
