What are the most common symptoms for bladder cancer?
Many early stage bladder cancer patients do not show any symptoms. The most common clinical presentation is blood in the urine or hematuria. Usually this is painless and the blood may be visible to the naked eye (gross hematuria) or can be seen only under the microscope (microscopic hematuria). Frequently the diagnosis of bladder cancer is delayed because bleeding is intermittent or attributed to other causes such as urinary tract infection or the intake of anticoagulants (drugs that block blood coagulation). However, a substantial proportion of these patients will have a significant problem such as kidney stones or tumors, urinary tract obstruction and bladder cancer.
