Carcinogenic

The term carcinogen refers to any substance or radiation that is an agent directly involved in the promotion of cancer or in the increase of its propagation. Carcinogens may increase the risk of getting cancer by altering cellular metabolism or damaging DNA directly in cells, which interferes with biological processes, and induces the uncontrolled, malignant division, ultimately leading to the formation of tumors.

Common examples of carcinogens are inhaled asbestos, certain dioxins, and tobacco smoke. Carcinogens can be found in everything from snack foods and drinks to certain types of plastic and everyday objects. All too often, a substance isn't identified as carcinogenic until it has been used or consumed by humans for many years.

Cooking food at high temperatures, for example grilling or barbecuing meats, can lead to the formation of minute quantities of many potent carcinogens that are comparable to those found in cigarette smoke.
