Can traditional epidemiology detect cancer risks caused by occupational exposure to pesticides?

In order to investigate the possible relationship between cancer and occupational exposure to pesticides, we reviewed the latest literature of the epidemiological studies in this area coming to the conclusion that, while several studies indicate a link between certain pesticides and certain tumors, this information is still insufficient, and further research on the health consequences of exposure to pesticides is needed. Moreover, provided there is a risk, it is often too limited to be detected by available epidemiological techniques. Therefore, in addition to the epidemiological studies, the development of new biology, gene technology and medical biotechnology methods may significantly enhance the specificity of the epidemiological studies. Thus, the fusion of molecular biology and epidemiology into molecular epidemiology may provide more specific methods for monitoring the occupational dependent carcinogenic risk of individuals and groups.
