Falling rates of lung cancer in men in the United States.

Lung-cancer incidence and mortality rates in the United States were calculated for the years 1973 to 1983. The historically increasing age-adjusted rates for white men levelled off in the late 1970s and fell between 1982 and 1983. These falls were seen for white men only. Both the incidence and mortality rates for women continued to rise with no hint of a reduction.
