Smoking and lung cancer
Lung cancer is directly related to smoking. Over 40 carcinogens have been identified in cigarette smoke. The risk of developing lung cancer is directly related to the number of cigarettes smoked. The change in consumption from unfiltered high tar cigarettes to filtered low tar cigarettes parallels the change in incidence from squamous cell carcinoma to
adenocarcinoma. There is a long interval between quitting smoking and elimination of lung cancer risk. Up to 40% of newly diagnosed lung cancer occurs in former smokers.
The risk of developing lung cancer is dose-response related: longer duration and heavier consumption patterns of smoking increase the likelihood of developing the disease. For example, a child who starts smoking aged 14 years or less is five times more likely to die of lung cancer than a person who starts aged 24 or more years, and 15 times more likely to die of lung cancer compared to someone who never smokes. Overall, smokers are ten times more likely to die from lung cancer than are non-smokers, and heavy smokers are 15 to 25 times more at risk than non-smokers.
The risk of developing lung and other smoking-associated cancers is related to total lifetime exposure to cigarette smoke, as measured by the number of cigarettes smoked each day, the age at which smoking began, and the number of years a person has smoked. Likewise, the risk of developing other smoking- related diseases, including chronic lung diseases and coronary heart disease, also increases with the amount of smoking a person has done.
The health risks associated with cigarette smoke are not limited to smokers: exposure to environmental tobacco smoke (ETS) significantly increases a nonsmoker's risk of developing lung cancer. Nonsmokers who live or work with smokers experience a 30 to 50 percent elevated risk for lung cancer.
Smokeless tobacco users are at increased risk for cancers of the oral cavity, particularly cancers of the cheek and gum, and evidence also suggests an association between use of smokeless tobacco and cancers of the larynx and esophagus. Pipe and cigar smokers experience substantially elevated risks for cancers of the oral cavity, larynx, pharynx, and esophagus, which equal and often exceed the risks observed in regular cigarette smokers. Pipe and cigar smokers experience a slightly increased risk for lung cancer; however, among pipe and cigar smokers who inhale, the risk of lung cancer is on the same order of magnitude found in cigarette smokers.
A smoker's risk of developing lung and other cancers can be reduced by quitting. The risk begins to decrease immediately after quitting and continues to decline gradually each year. Another benefit is that the risk of developing other cancers and chronic diseases associated with smoking is also reduced. The risk of coronary heart disease, for example, declines substantially within only a few short years following cessation. Women who quit smoking during the first trimester (3 months) of pregnancy substantially reduce the risk of such adverse pregnancy outcomes as low birth weight or stillbirth.
