One way that this occurs is through the ingestion of food mutagens. Sporadic cancers result from a gene-environment interactions where the environment includes endogenous and exogenous exposures. In this article, we define environment as dietary exposures in the context of gene-environment interactions.

For 17 years, LLNL researchers have been identifying these food mutagens, measuring their abundance in cooked foods typical of the Western diet, working to understand how they can trigger malignant tumors in laboratory animals that have been exposed to high mutagen doses, and estimating the importance of human exposures.

Competitive enzyme-linked immunosorbent assays (ELISA) with 50% inhibition by 0.4–6 pmol food mutagen were developed. The epitopes recognized by the antibodies have been characterized by ELISA using 52 synthetic analogues and metabolites of PhIP, 4,8-DiMeIQx, and other food mutagens.

By heating whatever food, hundreds of different mutagenic substances originate. The more protein food contains, the more mutagenics originate. And if we only live long enough, they cause cancer. ... The only way to effectively prevent cancer, is to prevent absorption of mutagenic substances from prepared food.
