Answer: Current smokers had an increased risk of fatal prostate cancer (RR = 1.14; 95% CI = 1.06, 1.19). The heaviest smokers had a 24% to 30% greater risk of death from prostate cancer than did nonsmokers. Conclusions. Observational cohort studies show an association of smoking with prostate cancer incidence and mortality.
