why do seemingly random things “give you cancer”?

Question

Every time I see someone touch oil or breathe in fumes or dust( or other dirty things), I always see “hes gonna get cancer” in comments. I always kind of just accepted it as truth, but do they actually give you cancer? like how can breathing in some dust make your cells divide weirdly and give you cancer?

Answer 1

Dust in old houses will probably have lead paint or asbestos. Alot of things like BBQ meats that have charred on them trigger the California 65 warning label that the contents might cause cancer. There are just a lot of things with harmful stuff in it.
