What are the causes of Bladder Cancer?

There are no known causes for bladder cancer, but it is found that absorbing cancer causing materials for a long time is one of the causes. Materials include chemicals in cigarettes. After those materials undergo metabolism inside the body, some will be excreted through the urine. and the bladder membrane will be in contact with them, which cause abnormal cell growth inside the bladder.


Furthermore, in places where Schistosomiasis (a kind of parasite causing cystitis) prevails, the cases of bladder cancer are more. Frequent consumption of preserved food or food with nitrite enhances the risk of getting bladder cancer.



Can symptoms of Bladder Cancer be recognized easily?

Some of the symptoms of bladder cancer are identical to those of cystitis, bladder stone or kidney stone, and the commonest symptoms are haematuria. This may not cause pain and in the early stage, it may occur every now and then. When the situation worsens, there may be blood clods in the urine, making one feel pain when one urinates or causing one unable to urinate. Should the tumour erode the neck of the bladder, the patient will develop urinary frequency and have difficulty in urinating or will feel the urinating being blocked.
