In patients with a history of smoking,
bladder cancer is the most common diagnosis of gross hematuria, and most tumors are found during cystoscopy. The risks of the procedure are low, and include, infection, trauma to the lower urinary tract, and bleeding. I would strongly suggest a complete work-up in your case and age group even if the bleeding has stopped. If you are young and a non-smoker, the incidence of bladder cancer is quite low, but a few simple tests can verify your situation.
