Secular trends in incidence and mortality of bladder cancer in China, 1990-2017: A joinpoint and age-period-cohort analysis.

The incidence of bladder cancer is increasing in men but mortality decreases in both sexes. Both the incidence and mortality in men substantially increase with age and period, while the rates in women increased with period since 2007. The period effect may indicate the increased risks to bladder cancer in Chinese men. Etiological studies are needed to identify the factors driving these trends of bladder cancer.
