Hematuria (blood in the urine)
Blood in the urine is the most common symptom of bladder cancer. It is generally painless. Although blood may be visible, in most cases it is invisible except under a microscope. In these cases, blood is found when your urine is tested by your health care provider.
Blood alone does not mean that you have bladder cancer. There could be many reasons for blood in the urine, such as a urinary tract infection or kidney stones. Microscopic amounts of blood might even be normal in some people.
Frequent Urination and Pain on Urination (dysuria)
Frequent or painful urination is less common. If you have these symptoms, and do not have a urinary tract infection, you should talk to your health care provider to find out if bladder cancer is the cause.
