In short
Blood in your pee — even once, even if it does not hurt — is the main symptom of bladder cancer. Needing to pee often or urgently, or repeated urine infections, also need a check. About 10,000 people are diagnosed in the UK each year. Smoking causes around half of cases. Stage 1 survival is over 95% when it is found early.
Blood can come and go. Do not wait for it to come back. GPs take visible haematuria in adults seriously.
Which symptoms should you report?
Visible blood is the headline. You do not need pain or clots.
- Blood in your pee — even once, even if painless
- Needing to pee very often or urgently
- Burning when you pee that is not a simple infection
- Urine infections that keep coming back
Why is smoking the biggest risk?
Chemicals in tobacco are filtered into urine and contact the bladder lining for years. Stopping smoking lowers the chance of new tumours even after a diagnosis.

Donate to cancer careIs this the same as kidney cancer blood in the urine?
The symptom overlaps. Urology tests look at both the bladder (camera) and the kidneys (scan) so the source is found.
Key takeaways
- Painless blood in the urine should be checked even once.
- Smoking causes around half of bladder cancers.
- Early-stage survival is over 95%.

The diagnosis, screening and treatment described here are routine in the UK. In Pakistan, Indonesia and Malaysia, poverty can put them out of reach. The Cancer Emergency Appeal raises funds towards clinically recommended care for patients who cannot pay; gifts go to the wider fund and do not buy a guaranteed treatment or result.
