Abstract: | Correlation and regression analyses were used to study effects of exogenic and endogenic epidemiological factors. The findings of the two methods were almost identical. Of epidemiological factors in males under 50 years of age most essential were smoking and drinking regime. With age, cancer of the bladder more frequently arises due to infravesical and urinary inflammation. In males over 70 years of age smoking and infravesical obstruction are leading causes. Smoking is a leading cause of bladder cancer in women of all age groups. A drinking regime is the second cause of bladder cancer in patients under 60 years of age, while inflammation is more essential for bladder cancer onset in patients over 60. |
