The international pictogram for chemicals that are sensitising, mutagenic, carcinogenic or toxic to reproduction. A carcinogen is any substance, radionuclide, or radiation that is an agent directly involved in causing cancer. This may be due to the ability to damage the genome or to the disruption of 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.
A carcinogen is a substance that is capable of causing cancer. Carcinogens do this by increasing the rate of cellular division, which increases the probability of abnormal DNA synthesis.There are many known carcinogens. Some of these include tobacco, pesticides, and asbestos.esson Summary. A carcinogen is a substance that is capable of causing cancer.
