where is the suprise there? EVERYTHING CAUSES CANCER! The water you drink, the food you eat! gas engines are just as dirty if not dirtier! and just as toxic! looks like journalism sensationalism to me!
Makes me wonder how many people got cancer of some type 4,000 years ago. Did they live long enough for it to be a risk? I guess back then they were issuing memos of "Proximity to lions causes premature death". Though, when you die at an average age of 40 I guess everything in life is premature.
