Differences in exposure to risk factors, such as prevalence of tobacco smoking, occupational exposure to carcinogens, and infection with Schistosoma haematobium are thought to be responsible for the observed global variability in incidence and histological type.[15]Richters A, Aben KKH, Kiemeney LALM.
