Exposure to certain hazardous chemicals like asbestos, uranium, arsenic, cadmium, chromium, nickel and some petroleum products can cause lung cancer. People also inhale these as toxic air pollutants from emissions from power plants or industry smokestacks, and sometimes from the workplaces.
What are the primary environmental factors leading to the development of cancer?
People who have certain jobs such as; painting, construction, pesticide and petroleum workers have an increased risk of cancer. Many studies have shown that exposure to asbestos, benzene, benzidine, cadmium, nickel, arsenic, radon and vinyl chloride in the workplace can cause cancer.
Which factor is the leading cause of lung cancer?
