Bladder cancer often has clear warning signs, but they can be easy to confuse with common urinary problems like infections, so any new or worrying symptom should be checked by a doctor promptly.

Main early symptom

  • Blood in the urine (hematuria) – urine may look pink, red, rusty, or cola‑colored, or blood may only show up on a lab test even when the urine looks normal.
  • It may come and go (appear for a few days, then disappear) and is usually not painful by itself.

Other urinary symptoms

These are common with bladder cancer but also overlap with infections or prostate problems.

  • Needing to pee more often than usual.
  • Feeling a sudden, strong urge to pee (urgency), even when the bladder is not very full.
  • Pain, burning, stinging, or itching when you pee.
  • Having to get up many times at night to pee.
  • Feeling like you cannot completely empty your bladder or having a weak urine stream.
  • Difficulty peeing or, rarely, not being able to pee at all.

Possible signs of more advanced disease

When bladder cancer is larger or has spread beyond the bladder, symptoms can be more general.

  • Persistent pain in the lower back or flank (often on one side).
  • Pain in the lower tummy, pelvis, or upper thigh.
  • Unintended weight loss and loss of appetite.
  • Extreme tiredness, feeling generally unwell, or weakness.
  • Swelling in the feet or ankles.
  • Bone pain or tenderness.

When to seek urgent care

Contact a doctor urgently (or same‑day service) if:

  • You notice blood in your urine, even once, and especially if it is not from menstruation or a known cause.
  • You have burning or frequent urination that does not improve after treatment for a urinary infection.
  • You cannot pass urine, or have severe lower back or tummy pain with urinary symptoms – this can be an emergency.

If you have any of these symptoms now, you should see a healthcare professional as soon as possible to get proper tests (like a urine test, imaging, or cystoscopy) rather than trying to self‑diagnose.
