Smokers who work with asbestos are how many times more likely to develop lung cancer than non-smoking, non-asbestos workers?

Smokers who work with asbestos are how many times more likely to develop lung cancer than non-smoking, non-asbestos workers?

• A. 10 times
• B. 50 times
• C. 5 times
• D. 100 times

Answer: (B)

The main idea is that smoking and asbestos exposure interact in a way that greatly multiplies lung cancer risk. When both factors are present, the risk isn’t just added together; they amplify each other, leading to a much higher chance of developing lung cancer than someone who neither smokes nor is exposed to asbestos. The commonly cited figure is about 50 times higher risk. So, a smoker with asbestos exposure is roughly fiftyfold more likely to develop lung cancer than a non-smoker with no asbestos exposure. This reflects how smoking damages lung tissue and helps carcinogens from asbestos do more harm, while asbestos fibers add direct cancer-causing stimuli. The other options underestimate or misstate the typical risk level seen in occupational health data.
