Smoking-related lung cancer rates are expected to drop dramatically over the next 50 years, but lung cancer will continue to be a significant health problem in the United States, says a University of Michigan researcher. Rafael Meza [...] utilized four independent models to project lung cancer rates for U.S. men and women aged 30 to 84 from 1964 to 2065. All models projected the impact of changes in smoking prevalence since the 1960s on past and future lung cancer mortality.
