Bladder Cancer

What is bladder cancer?

Bladder cancer is characterised by the development of abnormal cells in the lining of the bladder.2 There are three main types of bladder cancer:2

• Urothelial carcinoma, also known as transitional cell carcinoma (TCC), which develops in the cells of the bladder lining. It is by far the most common type of bladder cancer, accounting for about 90% of all cases.
• Squamous cell carcinoma, which begins in squamous cells of the bladder lining, and accounts for 4% of all bladder cancers.
• Adenocarcinoma, which begins in glandular cells in the lining of the bladder, and accounts for 2% of all bladder cancers.
