Abstract Despite significant efforts to limit exposure to silica, 494 new cases of silicosis were diagnosed in Quebec between 1988 and 2003. While the CSST acknowledges the existence of a relationship between silica exposure and certain cases of lung cancer, this view is not unanimously accepted by lung specialists. This study examines the literature concerning the relationship between silicosis, exposure to silica and lung cancer. Findings suggest that there is an increased risk of death due to lung cancer in silicotic persons. The data published to date also suggest that silica exposure represents a low risk factor for lung cancer at exposure concentrations that exceed the permitted limit based on North American standards. These results are broadly in agreement with the conclusions of the International Agency for Research on Cancer (IARC).
