Bladder cancer
Painless blood in the urine is the classic first sign — and needs a same-week workup. Most bladder cancers are caught at a non-invasive stage that's very treatable.
What to know first
- About 75% of bladder cancers are non-muscle-invasive at diagnosis.
- Cystoscopy (a scope look at the bladder) is the definitive test.
- Smoking is by far the largest modifiable risk factor.
When to see a doctor
- Any visible blood in the urine — even once, even painless
- New or persistent urinary urgency, frequency, or burning without infection
- Recurrent 'UTIs' in men, or UTIs that don't clear with antibiotics
