Susceptibility to the development of cancer depends on the balance between metabolic activation and detoxification of potential carcinogens in smokers [ figure 1 ].
Prolonged smokers, like smokinhsmoking for many years may also be at risk. The latter group is more likely to develop lung cancer as a result of a genetic mutation or abnormality. There are lifelong smokers who never get lung cancer and individuals who have never smoked who get lung cancer.
