Historically, some groups of chemists and laboratory workers did have elevated cancer risks because they were exposed to substances now known to be carcinogenic, such as benzene, aromatic amines, & some chlorinated solvents. Lab standards have now improved.
Notice that chemophobia rarely comes from chemists?
The people who spend their careers studying molecules, toxicology, exposure, and risk tend to be the least afraid of “chemicals.”
Why do you think that is?
