everything causes cancer.. i would much rather have a clear face than worry about the risk of BP or ponds cold cream. What acne has done to my face has destroyed my confidence and career probably for life. I think that is more important than a very small percentage of one product causing cancer. If you take care of your immune system and health that shouldnt happen. Everyone has cancer..its your immune system that quits and creates what you see to be cancer.. but everyone carries cancer and your immune system kills it ..so if you end up with cancer you better ask yourself WHY your immune system didnt kill those cancer cells.
