Written by HealthAnswers editorial team Medically reviewed by [HealthAnswers UK doctor review panel](https://healthanswers.co.uk/our-doctors/) Reviewed 3 July 2026 ## Quick answer What is bladder cancer? Bladder cancer is one of the commonest cancers in the UK — most often presents with blood in urine (visible or microscopic) with no pain. Smoking is the biggest risk factor. Diagnosis needs cystoscopy and biopsy — urine tests alone are not enough. Non-muscle-invasive bladder cancer is treated with removal via cystoscope (TURBT) plus BCG immunotherapy into bladder. Muscle-invasive disease may need bladder removal (cystectomy) or chemoradiotherapy. See a GP within 2 weeks for blood in urine — even once — especially if you smoke or are over 45. ## Who is this page for? This page is for people in the UK who want a plain-English overview of Bladder cancer, including when to seek help and what NHS care usually involves. It explains general information, not what is wrong with you personally. ## Who should skip this page? Skip this page if you need a diagnosis, a prescription, or emergency care. It cannot replace a GP, pharmacist, NHS 111 or 999. If you are in immediate danger, call 999; for urgent advice that is not life-threatening, call 111 in England, Scotland or Wales, or use your GP out-of-hours service in Northern Ireland. On this page 7 sections ## Key facts about bladder cancer - About 10,300 bladder cancer cases in the UK each year — 4th commonest cancer in men. - Painless visible blood in urine (haematuria) is the classic presentation — always needs investigation. - Smoking causes about half of cases — quitting reduces risk. - Occupational exposure to aromatic amines (dye, rubber industries) increases risk — past exposures matter. - Most bladder cancers are urothelial (transitional cell) carcinoma — superficial or invasive. ## Bladder cancer — never ignore blood in urine **Bladder cancer (urothelial carcinoma)** — **~10,300 UK cases/year** — **painless haematuria** is **cardinal sign**. **Men 3–4× commoner** — **smoking dominant risk** ## Risk factors - Smoking — 50% attributable - Occupational chemicals — rubber, dye, leather - Chronic schistosomiasis — rare UK - Previous pelvic radiotherapy - Lynch syndrome See [urinary tract infection](https://healthanswers.co.uk/conditions/urinary-tract-infection/) — **UTI can cause blood** — **but must exclude cancer if haematuria without clear infection or recurrent** ## Investigation pathway **2-week wait haematuria clinic:** - Cystoscopy — office flexible often first - Imaging — CT urogram - TURBT if lesion seen **Do not treat repeated antibiotics without cystoscopy** if **haematuria persists** ## Staging and grading **NMIBC (Ta, T1, CIS):** - Confined to mucosa/lamina propria - High grade CIS — flat aggressive — BCG essential **MIBC (T2+):** - Muscle invasion — systemic risk ## Treatment summary | Stage | Treatment | | --- | --- | | Low-risk NMIBC | TURBT + surveillance | | High-risk NMIBC | TURBT + BCG induction/maintenance | | MIBC | Radical cystectomy ± neoadjuvant chemo OR chemoradiotherapy | | Metastatic | Immunotherapy, ADCs, chemotherapy | ## Urinary diversion after cystectomy **Ileal conduit** — **urostomy bag** **Neobladder** — **internal pouch** — **selected patients** **Quality of life** — **specialist stoma nurses**, **peer support** ## Surveillance **Bladder cancer recurs in bladder** — **and upper tract** **Cystoscopy schedules** — **up to 10 years** **One episode red urine** — **GP referral** — **90% not cancer** — **but 10% need you to show up**. ## ! When to see a GP about bladder cancer See a GP within 2 weeks for any visible blood in urine — even one episode — or repeated urine tests showing blood without infection. Same-day if blood clots blocking urine flow, or haematuria with weight loss or bone pain. NICE 2-week wait urology referral for unexplained haematuria age 45+ or visible haematuria any age without UTI. Do not assume blood is infection until proven. ## Common questions about bladder cancer What are the symptoms of bladder cancer? Painless blood in urine — pink, red, or cola-coloured — most common sign. May be intermittent — one episode still needs investigation. Frequency, urgency, dysuria less common — overlap with UTI. Advanced — pelvic pain, weight loss, bone pain, leg swelling if obstructed. How is bladder cancer diagnosed? Cystoscopy — camera into bladder — gold standard. TURBT — transurethral resection — removes tumour and provides histology. CT urogram or ultrasound for upper tract. Urine cytology supplementary — not standalone screening. Staging — non-muscle-invasive (NMIBC) vs muscle-invasive (MIBC) determines treatment. How is non-muscle-invasive bladder cancer treated? TURBT complete resection. Intravesical BCG immunotherapy — weekly then maintenance — reduces recurrence and progression for high-risk NMIBC. Intravesical chemotherapy (mitomycin C) for intermediate risk. Surveillance cystoscopy schedule — intensive first 2 years. How is muscle-invasive bladder cancer treated? Radical cystectomy — bladder removal with urinary diversion (ileal conduit or neobladder) — or trimodal chemoradiotherapy preserving bladder in selected patients. Neoadjuvant cisplatin chemotherapy before surgery improves survival. Metastatic — immunotherapy (pembrolizumab), enfortumab vedotin. Can bladder cancer be prevented? Stop smoking — most important. Hydrate well. Workplace exposure reduction. No proven screening for general population. Recurrence common in bladder — lifelong cystoscopy follow-up after treatment. ## Sources - [NHS — Bladder cancer](https://www.nhs.uk/conditions/bladder-cancer/) - [Fight Bladder Cancer](https://fightbladdercancer.co.uk/) - [NICE — Bladder cancer](https://www.nice.org.uk/guidance/ng2)
