Bladder Cancer is a type of cancer that affects the urinary bladder, there maybe no early symptoms and signs but smoking is a risk factor. Once the diagnosis is established the right treatment can be administered.
The most common type of bladder cancer, known as urothelial cell carcinoma or transitional cell carcinoma,

. Other risks include exposure to chemicals, family history or being a Caucasian male.
The main function of the bladder is to collect and store urine produced by the kidneys. Its muscular walls stretches as the urine fills up.
