Warning Symptoms
- Blood in urine — often painless, may come and go, don't be falsely reassured if it resolves
- Increased urinary frequency
- Urgency to urinate
- Pain or burning on urination (less common than with infection)
- Pelvic pain (more advanced disease)
Major Risk Factors
| Risk Factor | Impact |
|---|---|
| Smoking | Accounts for roughly half of all cases — by far the biggest modifiable risk factor |
| Occupational chemical exposure | Certain dyes, rubber, and chemical industries increase risk |
| Chronic bladder irritation/infection | Long-term catheter use, chronic UTIs, certain parasitic infections (schistosomiasis) |
| Age | Most cases occur over 60 |
Diagnosis and Treatment
| Step | Detail |
|---|---|
| Urine cytology | Looks for abnormal cells in urine — supportive but not definitive |
| Cystoscopy | Camera examination of the bladder — gold standard diagnostic test |
| TURBT (transurethral resection) | Removes and samples the tumour — both diagnostic and initial treatment |
| Intravesical treatment (BCG) | Immunotherapy instilled directly into bladder for non-muscle-invasive disease |
| Radical cystectomy | Bladder removal for muscle-invasive or high-risk disease |
Never Ignore Painless Blood in UrineEven a single episode of blood in the urine, especially if painless, warrants investigation — this is the classic presentation of bladder cancer and should never be dismissed as 'probably just a UTI' without proper assessment, particularly in smokers or those over 50.
Smoking Cessation Reduces Risk Over TimeEven long-term smokers who quit see a gradual reduction in bladder cancer risk over subsequent years — it's never too late to benefit from stopping smoking.
Is blood in urine always cancer?
No — most cases of blood in urine have benign causes (UTI, kidney stones, exercise-related). However, because bladder and kidney cancer are important causes, thorough investigation is always warranted.
Does bladder cancer often come back after treatment?
Non-muscle-invasive bladder cancer has a significant recurrence rate (up to 50-70% over time), which is why regular cystoscopic surveillance is needed even after successful initial treatment.
