Not likely: The vast majority of lung cancer is caused by smoking - i.e. First hand cigarette smoke. Lung cancer is rare in people who have never smoked. If car exhaust were an important contributor we'd see far more cancer in people who had never smoked.

Watchout liver : Car fumes are detoxed by liver so keep detoxing your liver if u work in a field that involves inhaling car fumes a lot.

Any hydrocarbon can: ...Cause lung cancer. Any hydrocarbon combustion product, including car exhaust, will have carcinogens in it, but the volume and intensity of exposure, as well as the duration of exposure is several orders of magnitude less than that of a person who intentionally inhales cig smok for 20+ years, even if you live next to a busy street. Best advice? Don't smoke, and don't suck on a tialpipe.

Car fumes & cancer: Research has shown there is an epidemic of illnesses that are exacerbated by exhaust from vehicles, including cardiovascular disease, asthma, chronic obstructive pulmonary disease (COPD), and lung cancer.

Smoking: Tobacco smoking is the usual cause of lung cancer. About 10% of lung cancers may occur in non-smokers. Second hand smoke and exposure to radon gas are the next important causes. Of course genetic susceptibility always plays a role in all diseases, including lung cancer.

Mainly smoking: But a lot of other factors (most of which can nit be altered) may play a role. Over 85% of lung cancers are seen in smokers, so if you would like to decrease your chances of getting lung cancer (and also cardiovascular disease!) quit smoking now!

Possibly genetic,etc: Nonsmokers account for 15% of lung cancer cases, and these cases are often due to a combination of genetic factors, radon gas, asbestos, and air pollution including secondhand smoke. Asbestos can also cause mesothelioma, a cancer of the pleura or lining on the surface of the lungand diaphragm. The main type of lung cancer in nonsmokers is adenocarcinoma, particularly bronchoalveolar carcinoma.
