What is Bladder Cancer?
Bladder cancer occurs when there is abnormal cell growth in the urinary bladder.
About 90-95% of the cancers begin from the inner lining of the bladder (urothelium or transitional epithelium) and hence they are known as urothelial or transitional cell carcinoma.
When this abnormal cell growth is still within the inner lining of the bladder, it is called superficial bladder cancer.
When the growth invades the muscular layers of the bladder and enters the surrounding tissues, organs and lymph nodes, it is known as invasive cancer of the bladder.
The earliest sign of bladder cancer is hematuria without pain and other urinary symptoms.
Drinking large amounts of fluid, water in particular may reduce the risk of developing bladder cancer.
