title: [Measurement of occupational exposure in the research of cancer etiology].
abstract: When planning a study about the effect of occupational exposure on cancer incidence, two main aspects should be taken into account. In the first place, cancer is a disease of long latency. Secondly, the exposure to chemical products, and not the occupation itself, is responsible for the carcinogenic effect. Recently, some authors have developed methods to deal with these aspects in order to improve the validity of the associations which have been described between occupations and cancer. Job-exposure matrix and a method for quantifying the exposure to chemical products are new approaches to investigate the etiology of cancer, specially the part which can be attributed to chemical exposure at work.
