Occupational and non−occupational exposure in inhaled factors high risk for lung cancer.Lung cancer is the most common cause of cancer death throughout the world. In U.S. will cause an estimated 162.000deaths during 2008, in comparison with 121.000 deaths from, totally, colorectal, breast, and prostate cancer. The relationonly between occupational and non−occupational exposure in inhaled high risk factors and lung cancer, will reviewed inthis paper. The exposure to tobacco smoking is the main risk factor. However, not all lung cancer is smoking related. Twoto 10 percent of lung cancer cases occur in never smokers, with women more commonly affected than men. Additionalrisk factors for lung cancer include exposure to asbestos, haloethers, polycyclic aromatic hydrocarbons, nickel, and arse−nic. Interest has also focused on the potential roles of exposure to environmental tobacco smoke (ie, passive “smoking”)and to radon. The link between smoking and lung cancer was first suggested by Adler in 1912. Nowadays the inhalationof smoke, from cigarette, cigars and pipes, is estimated to be responsible for approximately 87 percent of cases of lungcancer, including 90 percent of cases in men and 79 percent of cases in women. Bronchogenic carcinoma is undoubtedlythe most preventable of the common forms of cancer because of the indisputable link between cigarette smoking andrisk of lung cancer. The relative risk increases with both the number of cigarettes smoked per day as well as the lifetimeduration of smoking, while additional factors include: a) age at onset of smoking, b) degree of inhalation, c) tar and nicotinecontent of the cigarettes and d) use of unfiltered cigarettes. According to large cohort and case−control studies, smokingcessation clearly decreases the risk of lung cancer among former smokers compared with current smokers from 20% to90%, depending upon the duration of abstinence. Many epidemiologic studies have shown that nonsmokers exposed toenvironmental tobacco smoke (passive smokers) demonstrate an increased risk of lung cancer depending on the cumula−tive exposures and the intensity of exposure. It seems that the risk for the development of lung cancer in response toenvironmental tobacco smoke may be influenced by genetics. Users of marijuana and cocaine are probably at increasedrisk for lung cancer, although the magnitude of risk has not been well quantified. Numerous occupational and environ−mental inhaled factors increase the risk of lung cancer. The best known factors are asbestos and radon; other exposuresinclude arsenic, bis−chloromethyl ether, chromium, formaldehyde, polycyclic aromatic hydrocarbons, hard metaldust, and vinyl chloride. Many of these factors act synergistically with tobacco smoke to produce lung cancer, and arealso independent risk factors in nonsmokers.
