A carcinogen is an agent that can produce cancer (a malignant growth or tumor that spreads throughout the body, destroying tissue). The EPA (Environmental Protection Agency) classifies chemical and physical substances according to their toxicity to humans.EPA classification system for carcinogensGroup A. Humans CarcinogensThis classification indicates that there is sufficient evidence from epidemiological studies to support a cause and effect relationship between the substance and cancer.Group B. Probable Human CarcinogenB: Substances are classified as B carcinogens on the basis of sufficient evidence from animal studies, and limited evidence from epidemiological studies.B: Substances are classified as B carcinogens on the basis of sufficient evidence from animal studies, with inadequate or nonexistent epidemiological data.Group C. Possible Human CarcinogenFor this classification, there is limited evidence of carcinogenicity from animal studies and no epidemiological data.Group D. Not Classifiable As To Human CarcinogenicityThe data from human epidemiological and animal studies are inadequate or completely lacking, so no assessment as to the substance's cancer-causing hazard is possible.Group E. Evidence Of Noncarcinogenicity For HumansSubstances in this category have tested negative in at least two adequate (as defined by the EPA) animal cancer tests in different species and in adequate epidemiological and animal studies. Classification in group E is based on available evidence; substances Amy prove to be carcinogenic under certain conditions.

The epidemiological triangle or epidemiological triad is a model describing the factors involved for an infectious disease. On one of each of the three ends is the host, the agent and the environment:The Host: the living organism which is capable of being infectedThe Agent: the factor that must be present or missing for the disease to occurThe Environment: the extrinsic force(s) or situation affecting the host's opportunity to be exposed to the agent

Epidemiological refers to the branch of medicine that deals with the incidence, distribution, and control of diseases in a population. It involves studying how diseases spread, their risk factors, and ways to prevent and control them on a large scale.
