Sometimes blood in your pee cannot be seen and is found during a urine test. This is called non-visible or microscopic haematuria. If you have urinary symptoms, your GP will ask you to give them a sample of urine. They test this for non-visible blood.
Some people may:
- have a burning feeling when they pee (pass urine)
- need to pee more often
- need to rush to the toilet to pee.
These symptoms are usually caused by an infection or an overactive bladder rather than cancer. Some people may need more tests to find out the cause of their urinary symptoms.
