What is the relationship between asbestos exposure and smoking?

The correct answer illustrates a critical understanding of the interaction between asbestos exposure and smoking, particularly regarding their combined effects on lung health. Studies have shown that when an individual who is exposed to asbestos also smokes, the risk of developing lung cancer is significantly heightened compared to individuals who are only exposed to either factor alone. This synergistic effect occurs because both smoking and asbestos exposure independently cause damage to lung tissue and increase the likelihood of mutations that can lead to cancer.

Individuals who smoke and are simultaneously exposed to asbestos face a much greater risk than those who do not smoke. This compounded risk underscores the importance of understanding both exposures in occupational and environmental health contexts. Hence, recognizing the increased risk of lung cancer when both factors are present is crucial for appropriate health assessments and interventions.

The other options either downplay the relationship between smoking and asbestos exposure or incorrectly suggest that one negates the other, which runs counter to established research in cancer epidemiology.
