Lung cancer is the leading cause of cancer death worldwide. Smoking is the main risk factor, but recent studies show an upsurge of professional and environmental factors in the genesis of this pathology. It is also the cancer most affected by occupational exposures, lungs are the front door many substances present in the workplace. This article presents all the pulmonary carcinogens as given by IARC (International Agency for Research on Cancer) classified as Carcinogenic agents with sufficient evidence in humans (group 1: carcinogen) and those known as agents with limited evidence in humans (group 2A: probably carcinogenic and group 2B: possibly carcinogenic). Although occupational lung cancer has no specificity for its clinical representation, there are some arguments of various kinds that can link this cancer to an occupational origin that will be examined throughout this article.
