>I'd dare to say that a not-so-phisically-active moderate-smoker living in a less polluted environment has way lower cancer risk than a bio-vegan athlete buddhist monk living in a polluted industrial hellhole. I always heard of general phrasing like "increases likelihood of cancer", but this sentence gives me the impression that there have been multiple conclusive studies on the direct contributions of urban pollution to individual cases of cancer. Can someone here who looked through such studies comment, or at least point to them by any chance?
