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?

DNA has instructions on how to build and operate a cell/tissue/organ/system/organism. It is a chemical, as are all the biological processes. Some chemicals can damage DNA or the mechanisms, resulting in mutations. Some mutations are ‘caught’ by the cell’s error-detection mechanisms and corrected or the cell can self-destruct. Others interfere with the mechanisms that control division or that receive signals from outside to control that division.
So if you have a robot that ordinarily can self-replicate but will shut down on receiving a signal or detecting internal corruption. If its code is damaged in such a way that it will keep replicating independent of receiving the signal to replicate, and doesn’t respond to a shutdown signal then you have a problem.
The comments sometimes are exaggeration because that’s the nature of online comments. Many chemicals in very large doses can cause cancer in the lab, but realistically they result in poisoning/toxicity.
