• Blood in the urine (hematuria)

This is the most common symptom of bladder cancer. It can occur suddenly and may come and go. Your urine may look pink, red, or brown from time to time; also, you may notice blood clots in your urine.

If you see blood in your urine, it is important you talk to your GP.

Sometimes, blood in the urine cannot be seen with the naked eye and is detected with a urine test; this is called microscopic hematuria.

• Urinary symptoms

Occasionally, people with noninvasive bladder cancer experience a burning sensation when urinating or feel the need to urinate more frequently or with greater urgency. These symptoms are usually caused by an infection rather than by cancer.

There are different causes behind these symptoms such as an infection or stones in the bladder or kidney. If you have any of these symptoms, it is important for you to talk to your GP immediately.
