This is the authors' abstract. We don't add key points for this paper.

Background: Bladder cancer is one of the most common cancers worldwide and its incidence and mortality rates vary globally due to genetic variation, population age and exposure to risk factors. In the present study we aim to report national and subnational incidence of bladder cancer in Iran between 2003 and 2015.Methods: This population-based study investigate the age-standardized incidence rates (ASRs) of bladder cancer between 2003 and 2015 in Iran and its 32 provinces using last updated data from national cancer registry system of non-communicable disease center of Iran Ministry of Health, and Medical Education. Results: ASR of bladder cancer increased from 8.35 in 2003 to 13.57 in 2015 in men. ASR of bladder cancer also showed a mild increase in females, 2.12 in 2003 versus 2.86 in 2015.Conclusion: In conclusion, we observed an increasing trend of bladder cancer incidence in Iran, highlighting the disease as a potentially major health problem in the future. Therefore, it is necessary for health organizations to implement effective educational, preventive and therapeutic programs in the country to prevent further increase of disease burden.
