ABSTRACT
It is retrospective and hospital based case control study which was conducted in the federal city of Islamabad in Pakistan in order to assess the risk factors of the urinary bladder cancer. This study was based on the 100 controls and 50 cases comprising 150 subjects which were selected for interview from the two hospitals and required information like gender, age, smoking habits, family history of cancer, etc., was achieved. Both the descriptive and analytical approaches were used to find out the dominating risk factors of the disease. Odds ratios and 95 % Confidence Intervals were obtained for analytical purpose by using the binary logistic regression model. Three factors including cigarette smoking, source of drinking water and fried items were found to be significant having odds ratios and 95% confidence intervals of (17.158, 6.244- 47.147), (0.192, 0.061- 0.603) and (12.206, 3.291- 45.275), respectively. The study revealed that cigarette smoking, consumption of tap water and high use of fried items increases the risk of developing bladder cancer. On the other hand, the use of government provided for drinking purpose is a protection against the urinary bladder cancer as compared to tap water.
