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!
Reads as if a greenie wrote it, singing the praises of ULSD and particulate filters. If any human lives long enough, he/she will get cancer. We all have cancer cells in our bodies, just a question of when they go active. The only enjoyable thing that does not seem to cause cancer is sex. Of course I would ignore that study entirely....
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.
