Primary carcinoma of the lung was an uncommon cancer until the
1930s. At that time a dramatic increase in the incidence of lung cancer
began that has not yet abated. Lung cancer is now the most common
cause of cancer mortality in both males and females.
Lung cancer also occurs in association with occupational and environmental
exposure to carcinogenic agents other than tobacco smoke.13
These include arsenic, asbestos, beryllium, chloromethyl ethers,
chromicin, hydrocarbons, mustard gas, nickel, and radiation.
It is surprising that the vast majority of cigarette smokers, including
heavy smokers, do not develop lung cancer. This suggests that cancer
formation is dependent on an inherited predisposition or cofactors,
such as additional carcinogens.
