- Bladder cancer develops when cells in the bladder lining grow out of control. Most tumours start in urothelial cells.
- Visible blood in the urine is the main warning sign. It may be painless, happen only once and then temporarily disappear.
- Blood in the urine does not automatically mean cancer; an infection, stone, prostate problem or another condition may also cause it. Investigation is still needed.
- A single urine test does not establish the diagnosis. Imaging, an examination inside the bladder and tissue testing are usually needed.
- Treatment and outlook depend on the type, grade and stage, particularly whether the tumour has grown into the bladder muscle and whether it has spread.
- Non-muscle-invasive bladder cancer is often removed through the urethra and sometimes treated with medicines put into the bladder. Regular examinations inside the bladder remain important because the disease may return.
- Muscle-invasive disease may require a combination of chemotherapy, surgery or radiotherapy. The treatment team discusses what is most suitable medically and personally.
- Smoking is the main avoidable risk factor. Stopping also helps after diagnosis and improves overall fitness for treatment.
