Taking Steps to Reduce Rates of Silica-Related Lung Cancer | Lung Cancer Dispatch | Scoop.it

Silica is a chemical found in sand and quartz and used in a multitude of industrial applications. Inhalation of silica dust can occur in a number of occupations and increases the risk of lung cancer. A recent review highlights new developments in understanding the health effects of silica exposure and recommends steps to reduce silica-related illness and death. Studies documenting the health risks associated with different levels of silica exposure have enabled evidence-driven regulations. Federal regulators are considering lowering the permissible occupational exposure to silica for workers, a measure that could cut the number of silica-related deaths in half. The review authors also recommend that workers exposed to silica who also smoke undergo computed tomography (CT) scans to screen for lung cancer starting at age 50 years.
