Occupations with long-term exposure to some chemical substances are prone to lung nodules. In addition, long-term smoking or being in an air-polluted environment will also lead to a high incidence of lung nodules.
Lung nodules refer to focal lung shadows with a diameter of less than or equal to three centimeters in the lungs. Lung nodules may be related to long-term exposure to chemical substances, if the work is often exposed to asbestos, vinyl chloride, radon and other environments, these chemicals will produce an immune response after being inhaled into the lungs, and the inflammation will be formed through the parcel of the mechanization or the formation of granulomas in the form of lung nodules.
The occurrence of lung nodules is also related to smoking and air pollution. If you work in a polluted environment, such as ore mining, metallurgy, cement manufacturing, flour milling, etc., you will inhale some dust, which will also increase the incidence of lung nodules.
Lung nodules are categorized into benign nodules and malignant nodules, and should be actively examined to clarify the nature of symptomatic treatment.
