How does smoking affect the risk of developing lung cancer related to asbestos?

Smoking significantly increases the risk of developing lung cancer, particularly when combined with asbestos exposure. Asbestos fibers have a known carcinogenic effect, which means they can lead to the development of cancer. When an individual who has been exposed to asbestos also uses tobacco, the risk of lung cancer multiplies. This is primarily because smoking damages the lungs and weakens the respiratory system while enhancing the carcinogenic effects of asbestos fibers.

The combination of both factors—smoking and asbestos exposure—creates a synergistic effect, leading to a higher likelihood of lung cancer than either risk factor alone. Studies have shown that individuals who smoke and are also exposed to asbestos have a significantly higher incidence of lung cancer compared to non-smokers who are exposed to asbestos, underscoring the necessity of awareness regarding these risks in occupations involving asbestos exposure.
