Chemical Carcinogens

A carcinogen is a substance, organism or agent capable of causing cancer. Carcinogens may occur naturally in the environment (such as ultraviolet rays in sunlight and certain viruses) or may be generated by humans (such as automobile exhaust fumes and cigarette smoke). Most carcinogens work by interacting with a cell’s DNA to produce mutations.

This course is intended to inform and provide information on types of cancers, how they are caused and what you can do to prevent them.
