How does small cell lung cancer affect women differently than men?

Lung cancer develops in men more often than in women. About 1 in 16 women will get lung cancer at some point in her life, versus 1 in 13 men. This larger incidence and number of deaths in men is not likely due to differences in biology between the sexes, but rather the higher smoking rate among men versus women. This incidence rate drops dramatically if you only look at the occurrence in non-smokers.
