How much more common is lung cancer in people exposed to asbestos compared to those not exposed?

Lung cancer is significantly more prevalent among individuals exposed to asbestos compared to those who have not been exposed. Research indicates that asbestos exposure can increase the risk of developing lung cancer by a factor of around five. This heightened risk is due to the carcinogenic properties of asbestos fibers, which can cause cellular damage leading to cancer, particularly in the lungs. The latency period for asbestos-related diseases also contributes to the risk, as symptoms may not arise until years after the initial exposure.

The specific figure of five times more common reflects extensive epidemiological studies that have thoroughly documented the correlation between asbestos exposure and lung cancer incidence. This established relationship aids in understanding why strict guidelines and protective measures are emphasized in the handling of asbestos in occupational settings.
