Hematuria is the most common and earliest symptom of bladder cancer, with 85% of patients experiencing intermittent gross hematuria which can decrease or stop on its own, often giving patients a false impression of improvement or cure, thus delaying treatment. Sometimes, hematuria is also found under a microscope, and the amount of bleeding is not necessarily consistent with the size, number, or malignancy of the tumor. The hematuria from bladder tumors can initially be mild, and other symptoms such as frequent urination, urgency, and painful urination may also occur; these are all manifestations of bladder tumors.
