===Risk factors===


Exposure to environmental carcinogens of various types is responsible for the development of most bladder cancers. Tobacco use (specifically cigarette smoking) is thought to cause 50% of bladder cancers discovered in male patients and 30% of those found in female patients. Thirty percent of bladder tumors probably result from occupational exposure in the workplace to carcinogens such as [[benzidine]]. Occupations at risk are metal industry workers, rubber industry workers, workers in the textile industry and people who work in printing. Some studies also suggest that auto mechanics have an elevated risk of bladder cancer due to their frequent exposure to hydrocarbons and petroleum-based chemicals.<ref>[http://jnci.oxfordjournals.org/cgi/content/abstract/81/19/1480 Occupational Risks of Bladder Cancer in the United States: II.

Hairdressers are thought to be at risk as well because of their frequent exposure to permanent hair dyes. It has been proposed that hair dyes are a risk factor, and some have shown an odds ratio of 2.1 to 3.3 for risk of developing bladder cancer among women who use permanent hair dyes, while others have shown no correlation between the use of hair dyes and bladder cancer. Certain drugs such as [[cyclophosphamide]] and [[phenacetin]] are known to predispose to bladder TCC.  Chronic bladder irritation (infection, bladder stones, catheters, [[bilharzia]]) predisposes to squamous cell carcinoma of the bladder. Approximately 20% of bladder cancers occur in patients without predisposing risk factors. Bladder cancer is not currently believed to be heritable (i.e., does not "run in families" as a consequence of a specific genetic abnormality).

==[[Bladder cancer epidemiology and demographics|Epidemiology and Demographics]]==
The treatment of bladder cancer depends on how deep the tumor invades into the bladder wall. Superficial tumors (those not entering the muscle layer) can be "shaved off" using an electrocautery device attached to a [[cystoscope]]. [[Immunotherapy]] in the form of [[Bacillus Calmette-Guérin|BCG]] instillation is also used to treat and prevent the recurrence of superficial tumors.<ref>{{cite journal | volume=353 | pages=1689&ndash;94 | year=1999 | issue=9165 |
title=BCG immunotherapy of bladder cancer: 20 years on. | url=http://linkinghub.elsevier.com/retrieve/pii/S0140673698074224}}</ref>
BCG immunotherapy is effective in up to 2/3 of the cases at this stage. Instillations of [[chemotherapy]] into the bladder can also be used to treat superficial disease.


Untreated, superficial tumors may gradually begin to infiltrate the muscular wall of the bladder.  Tumors that infiltrate the bladder require more radical surgery where part or all of the bladder is removed (a [[cystectomy]]) and the urinary stream is diverted.  In some cases, skilled surgeons can create a substitute bladder (a neobladder) from a segment of intestinal tissue, but this largely depends upon patient preference, age of patient, [[renal function]], and the site of the disease.
==[[Bladder cancer risk factors|Risk Factors]]==


A combination of [[radiation]] and [[chemotherapy]] can also be used to treat invasive disease.  It has not yet been determined how the effectiveness of this form of treatment compares to that of radical ablative surgery.
==[[Bladder cancer screening|Screening]]==


There is weak observational evidence from one very small study (84) to suggest that the concurrent use of [[statin]]s is associated with failure of BCG immunotherapy.<ref>{{cite journal | volume=355 | pages=2705&ndash;7 | year=2006 | issue=25 |
