CARCINOGENS:

Carcinogens:
A carcinogen is a substance that is directly involved in causing cancer. This may have something to do with the fact that it has the ability to damage the genome, or disrupt the cellular metabolic processes. Several radioactive substances are considered carcinogens, but their carcinogenic activity is attributed to the radiation, for example gamma rays and alpha particles, which they emit. Common examples of non-radioactive carcinogens are inhaled asbestos, certain dioxins, and tobacco smoke. It is equally likely to arise in both natural and synthetic substances. Carcinogens are not necessarily immediately toxic, therefore their effect can be insidious
