Any cancer-producing substance or organism, such as polycyclic aromatic hydrocarbons, or agents such as certain types of irradiation. A cancer ‘hazard’ is an agent that is capable of causing cancer under some circumstances, while a cancer ‘risk’ is an estimate of the carcinogenic effects expected from exposure to a cancer hazard. A carcinogen is dangerous once it overwhelms these repair mechanisms, and for that, it clearly makes a difference whether you take a single large dose or many small ones. Usually, microwaves, radio waves, infrared light, and visible light are not considered carcinogenic because the photons don't have enough energy to break chemical bonds. 7 years ago.

A carcinogen can increase that chance of mutation and cancer initiation. A person's risk of developing a cancer, then, depends on carcinogen, the type and amount of exposure, and their own genetic susceptibility (which you can't control). These substances cause changes in a cell's DNA, either directly or indirectly. But it's not the only thing linked with the disease, as Ella Walker reveals..
