Yeah, radiation treatments do exactly this. So to some extent does chemo: they kill dividing cells by damaging their dna, relying on killing tens of thousands of cancer cells for every non-cancerous cell. But there are a lot more non-cancerous cells, sooo.... Fairly famous picture of a truck driver who spent 40 years with UV only hitting one side of his face: Stuff that causes oxidative damage, or ionizing radiation, both do this. Smoke has lots of activated molecules that cause oxidative damage. To a lesser extent, the taste we like in BBQ does, too: we used to smoke meats in part because it filled them with chemicals that killed bacteria much faster than they damaged us.
