Health risks associated with excessive warnings about alleged cancer risks

As the adage states, "when everything is dangerous, nothing is." If the word carcinogen (cancer-causing agent) is used to designate a spectrum of products, chemicals, and other environmental exposures, then the classification cancer causing when referring to the results of human epidemiological studies becomes meaningless. Thus, the emerging "carcinogen-of-the-week" phenomenon is counterproductive in preventing the toll of human cancer in that it diverts attention from real causes.
