Lung cancer is the most common cancer in men and the fifth most common in women, even causing more cancer-related deaths in women than breast cancer. The incidence of lung cancer is strongly correlated with cigarette smoking, with about 90% of lung cancers arising as a result of tobacco use. Uncommon before the 1930s, lung cancer incidence began to rise during the 1930s as tobacco smoking became more popular. Public education programs about the dangers of cigarette smoking and effective smoking cessation programs have led to decreases in lung cancer rates in many developing countries.
