occurs when abnormal bladder cells grow and divide beyond their usual boundaries. Most often these cells start to grow on the inner layer of the bladder; however, sometimes this growth can expand into the deeper bladder layers, making the cancer increasingly difficult to treat.
While the symptoms of
There exist five types of
- Transitional cell (urothenlial) carcinoma –occurs in the cells that line the inside of the bladder and is the most common type of
, impacting 95 percent of patients.
– occurs in squamous cells, which usually appear in your bladder in response to infection and irritation. In the United States, only about one to two percent of bladder cancers are squamous cell carcinomas.
– occurs in cells that make up mucus-secreting glands in the bladder. Only about one percent of bladder cancers are adenocarcinomas.
- Small cell carcinoma – occurs in nerve-like cells called neuroendocrine cells. Less than one percent of bladder cancers are small-cell carcinomas.
- Sarcoma – this type of
is very rare and occurs in the muscle cells of the bladder.

- Though it is more prevalent in men, studies have shown that women are more likely to present advanced tumors and have a worse prognosis than men at almost every of the disease.
- The 5-year survival rate for women is equal to the 10-year survival rate for men.
