Answer

Worldwide, bladder cancer is diagnosed in approximately 275,000 people each year, and about 108,000 die of this disease. In industrialized countries, 90% of bladder cancers are TCC. In developing countries—particularly in the Middle East and Africa—the majority of bladder cancers are SCCs, and most of these cancers are secondary to Schistosoma haematobium infection. Urothelial carcinoma is reported to be the most common urologic cancer in China.

In Africa, the highest incidence of SCC has been seen in schistosomal-endemic areas, notably Sudan and Egypt, where SCC ranges from two thirds to three quarters of all malignant tumors of the bladder. In recent years, a few studies from Egypt have shown a reversal of this trend due to the better control of schistosomiasis in the region, whereas in other parts of Africa the association is unchanged. [10, 51, 52] Increased smoking incidence is believed to have contributed to the shift in Egypt toward TCC, which has a stronger smoking association.
