Non-invasive bladder cancer is a cancer that is only in the inner lining of the bladder. Invasive bladder cancer is cancer that has spread into the deeper walls of the bladder. When the cancer has spread outside the bladder to other parts of the body, this is known as advanced bladder cancer. Treatment for invasive and advanced bladder cancer is different to the treatment for non-invasive bladder cancer.
Blood in the urine (haematuria)
This is the most common symptom of bladder cancer. It can happen suddenly and may come and go. Your urine may look pink, red or occasionally brown, or you may see streaks or clots of blood in it.
If you see blood in your urine, it’s very important to get it checked by your GP straight away.
Sometimes, blood in the urine can’t be seen and is picked up in a simple urine test. This is called non-visible or microscopic haematuria. If you have urinary symptoms doctors usually check your urine for non-visible blood..
Occasionally, people with non-invasive bladder cancer experience a burning feeling when they pass urine or feel the need to pass urine more often or urgently. These symptoms are usually caused by infection rather than cancer. But some people may need more tests so a diagnosis can be made.
Pain in the lower part of the tummy or back
This is less common, but it may occur in some people.
