ZT:

Across the developed world, 91% of lung cancer deaths in men during the year 2000 were attributed to smoking (71% for women).^[22] In the United States, smoking is estimated to account for 87% of lung cancer cases (90% in men and 85% in women).^[23] Among male smokers, the lifetime risk of developing lung cancer is 17.2%; among female smokers, the risk is 11.6%. This risk is significantly lower in nonsmokers: 1.3% in men and 1.4% in women.^[24]
