Long-term exposure to radon can lead to which health issue?

Long-term exposure to radon is primarily associated with an increased risk of developing lung cancer. Radon is a colorless, odorless gas that forms naturally from the decay of uranium in the soil. When inhaled, radon and its decay products can damage lung tissue, leading to mutations that contribute to cancer development over time. This risk is particularly heightened for current and former smokers who are exposed to radon, as their risk of lung cancer is already elevated due to tobacco use.

While radon can be a concern in various environments, its most significant health impact is on the lungs, making lung cancer the principal health issue correlated with prolonged exposure. Other options may relate to different environmental hazards or health risks but do not reflect the specific consequences of radon exposure accurately. For instance, heart disease and respiratory issues are influenced by a variety of factors, and skin cancer typically arises from UV radiation exposure rather than radon. Thus, lung cancer remains the critical health concern associated with radon.
