A cooperative study of urinary bladder cancer morbidity in Kuibyshev and Tambov Provinces was conducted. A higher morbidity level was established in the latter area. However, morbidity growth rate was higher both in the whole population and individual age and sex groups in Kuibyshev Province. The results suggest that epidemiologic studies of bladder neoplasia should be continued in said areas.
