Umm, no. Acetone (and other ketones) are made by the body. Some diseases are
diagnosed by finding the smell of acetone on the breath.
Also, the solvent of nail polish and the chief ingredient of nail polish
remover, used daily by hundreds of millions of women, is acetone. There
haven't been too many reports of women dying of cancer of the fingers.
The carcinogenic solvents are largely chorinated hydrocarbons, like the
now-banned carbon tetrachloride. Some dry cleaning solvents were also banned.
Liver cancer is the typical issue with chorinated solvents, just as it is with
alcoholism.
