The primary early symptom of bladder cancer is hematuria, typically characterized by painless, intermittent gross hematuria throughout urination, and sometimes microscopic hematuria. Hematuria may occur only once or last from one day to several days, and it can spontaneously decrease or cease.

Some patients may mistakenly believe they are cured due to the coincidence of hematuria stopping after taking medication. In other patients, hematuria may reappear after a period of time. The color of hematuria can range from light red to dark brown, often appearing dark red or described as resembling meat-washing water or tea.

The amount of bleeding and the duration of bleeding are not proportional to the malignancy, size, extent, or number of the tumor. Hematuria is the most common early symptom of bladder cancer, which can be definitively diagnosed through bladder ultrasound and cystoscopy.

If it is an early-stage bladder tumor, transurethral resection of the bladder tumor can be performed, followed by postoperative instillation therapy. This is a type of malignant tumor with a very good prognosis.
