• A. True
• B. False
• C. Not sure
• D. Cannot be determined

Answer: (A)

Painless hematuria is the classic presenting symptom of bladder cancer. The tumor bleeds into the bladder lumen, and this bleeding often occurs without pain because the bladder wall’s sensory nerves are not strongly activated by tumor growth, so blood in the urine can appear without discomfort. Hematuria may be microscopic or visible as gross blood, which is why many patients first seek evaluation after noticing blood in the urine rather than pain. While other urinary symptoms like frequency or urgency can occur, they are less characteristic as the initial sign and are more commonly seen with infections or stones. Painful hematuria can happen with other conditions, but the most common initial presentation in bladder cancer is painless hematuria. Thus, the statement is true.
