Background: Approximately 5-10% of human cancers are thought to be caused by occupational exposure to carcinogens. Compare to other cancers, bladder cancer is most strongly linked to occupational exposure to chemical toxins. This study has been performed to understand which occupations and exposures are related to bladder cancer in Iran. Materials and Methods: This study is a case-control study which is conducted on cases with bladder cancer (160 cases) diagnosed in Baharlou hospital in 2007-2009. One hundred sixty cases without any occupational exposure were considered as controls matched for demographic characteristics. Demographic data and characteristics of occupation were compared. Results: Mean age of cases and controls were 63.7 and 64 years, respectively (P = 0.841). History of urinary tract stone had significantly difference in two groups (P = 0.039). Occupations such as bus and truck driving, road and asphalt making, mechanics, working in refinery and Petrochemical, plastic, metal manufactory, welding, and pipeline founded a higher risk for bladder cancer rather than controls. Conclusion: Our findings on Iranian workers are concurrent and compatible with findings of previous reports about occupational and environmental risk factors of bladder cancer. Although our study population was not little, further studies are needed to declare the risk of working in some occupations such as drivers and metal factories for bladder cancer.
