During the last decade, there has been increasing interest in the use of biomarkers in cancer epidemiology to enhance exposure assessment, to gain insight into disease mechanism, and to understand acquired or inherited susceptibility.

In this paper we are discussing the advantages, disadvantages, and logistical considerations in using biomarkers to answer research questions.
