What is bladder cancer?
Bladder cancer occurs when cells in the bladder become abnormal and grow and divide out of control.
Nearly all bladder cancers begin in the cells of the mucous membrane, which lines the bladder. There are two types of tumours:
Non-invasive tumours (superficial tumours) — The cancerous cells are only found in the lining of the bladder (urothelium), and have not invaded deeper layers. One type of non-invasive cancer is carcinoma in-situ.
Invasive tumours: The cancer has spread beyond the urothelium.
Bladder cancer symptoms
The most common symptom of bladder cancer is blood in the urine (haematuria). This is usually not painful, and it can occur suddenly.
