Bladder cancer survival rates - Bladder cancer continues to be a disease of great importance. He is responsible for approximately 3.5% of all malignancies in the world in 1980. In 1985. bladder cancer, according to estimates, was 11 th place among the most common cancers in the world, while he remains the eighth most common cancer occurring in men, with is expected to increase to 243.000 new cases. At the age of seventy years, comes the peak incidence of bladder cancer and the ratio of incidence between men and women is estimated as three to one. The incidence of bladder cancer tended to increase in almost all European nations, especially among the male population. 

In Denmark, where the annual incidence rate among the highest in the world, in 45 cases per 100,000 among men and 12 cases per 100,000 women, the latest trend implies an increase in incidence by 8-9% every 5 years. 

In Asia, the highest incidence among Chinese in Hong Kong had a strong tendency to decrease, but at this time in both sexes of the population of this region the incidence of bladder cancer is still far exceeds that of other parts of Asia and twice the incidence of the Chinese population of Shanghai and Singapore . Incidence of bladder cancer among Chinese residing in Hawaii is also extremely high. 

Cigarette smoking is the single most important etiologic factor in the development of bladder cancer and occupational exposure in second place. According to calculations by cigarette, smoking is responsible for one third of all cases of bladder cancer spread outside the region Shistosomal infection. Number of cases of bladder cancer in 1985 attributable to smoking tobacco than 75.000 worldwide, and can explain 50% of all cases of bladder cancer among the peoples of Western countries. The fact that all individuals who smoke with roughly the same addiction to tobacco products involve different levels of incidence of bladder cancer suggests that genetic factors are important in the management of susceptibility to the disease. Two aromatic amine, 4-amino befell and 2-naphtha lamina are carcinogenic substances related to smoking, they are found in higher concentrations in the "black tobacco" (air-dried) than in "mixed tobacco" (smoke-drying). Passive smoking increases levels of adducts in blood, and the dose-response formation of adducts in turn, was found to be associated with increased risk of cancer of the bladder. Higher levels of formation of adducts were found in smokers who are slow acetylates compared with those who are regarded as fast acetylates, suggesting that genetically inherited status may be an important biomarker of susceptibility.
