Hi I am due to have a breast augmentation on the 26th August using 400 cc polyurethane coated tear drop implants. After a lot of reading and worrying I am now scared to death that these implants will give me cancer. There is evidence to say this polyurethane when exposed to rats caused cancer; my real concern is what happens to the polyurethane does it dissolve and my body absorbs it?! Are the really approved by the same people who approved PIP i am terrified! My implants have been ordered help!
