Bladder cancer

Bladder cancer starts in the lining of the bladder. The bladder is part of the body system that filters waste products out of your blood and makes urine (wee). This is called the urinary system.

What is bladder cancer?

Bladder cancer starts in the inner lining of the bladder. The bladder stores urine and is in the lower part of your tummy (abdomen).

Risks and causes of bladder cancer

Getting diagnosed with bladder cancer

You usually start by seeing your GP. They ask about your symptoms and may examine you. They then might refer you to a specialist. The tests you may have include urine tests, a test to look inside your bladder (cytoscopy) and scans.

Stages, types and grades of bladder cancer

The main type of bladder cancer is urothelial bladder cancer. The stage tells you about the size of the cancer and whether it has spread. The grade means how abnormal the cells look under the microscope.
