What risk factor is associated with the combination of smoking and asbestos exposure?

The combination of smoking and asbestos exposure significantly amplifies the risk of developing lung cancer. Research indicates that individuals who are exposed to asbestos while also being smokers face a 50-90 times increased risk of lung cancer compared to non-smokers who are not exposed to asbestos. This elevation in risk is attributed to the synergistic effects of asbestos fibers and the carcinogenic compounds present in tobacco smoke, both of which contribute to cellular damage and inflammation in lung tissue.

In contrast, those who are only exposed to asbestos or are just smokers do not face the same level of risk as the concurrent combination. The stark increase in risk associated with both factors emphasizes the importance of preventive measures and health monitoring for individuals in occupations that may involve asbestos exposure and who smoke. Understanding this risk factor is crucial for asbestos project monitors when assessing health and safety conditions on job sites.
