Summary of Key Points

Role of Environmental Agents in the Etiology of Human Cancer

• Although the causes of many human cancers remain unidentified, cumulative data support the opinion that environmental or dietary agents are the principal cause of human cancers.

• Cigarette smoking could be responsible for 25% of all cancers in the United States.

• Chemical carcinogens include aromatic amines, benzene, aflatoxins, tobacco chemicals, and chemotherapeutic agents.

• Radiation carcinogens include ultraviolet radiation, ionizing radiation, and radon.

• A number of metal carcinogens have been identified, including arsenic, nickel, cadmium, and chromates. These carcinogens have been associated largely with occupational exposures.

• Fibers (e.g., asbestos and silica) and dusts are well established as etiologic agents in lung cancers and mesothelioma.
