Bladder cancer causes::There are many causes for Bladder cancer, the following factors increase a person's risk of developing a bladder cancer:

• Smoking is the single greatest risk factor for bladder cancer,it is the main known cause of urinary bladder cancer: in most populations, smoking causes over half of bladder cancer cases in men and a sizeable proportion in women. Smokers have more than twice the risk of developing bladder cancer as nonsmokers. There is a linear relationship between smoking and risk, and quitting smoking reduces the risk. In a 10-year study involving almost 48,000 men, researchers found that men who drank 1.5L of water a day had a significantly reduced incidence of bladder cancer when compared with men who drank less than 240mL (around 1 cup) per day. The authors proposed that bladder cancer might partly be caused by the bladder directly contacting carcinogens that are excreted in urine. It is postulated, therefore, that by drinking higher quantities of water, urine is more dilute, thereby reducing the chance of disease. Thirty percent of bladder tumors probably result from occupational exposure in the workplace to carcinogens such as benzidine. 2-Naphthylamine, which is found in cigarette smoke, has also been shown to increase bladder cancer risk. 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. 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. 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.
• Chemical exposures at work: People who regularly work with certain chemicals or in certain industries have a greater risk of bladder cancer than the general population. Organic chemicals called aromatic amines are particularly linked with bladder cancer. These chemicals are used in the dye industry. Other industries linked to bladder cancer include rubber and leather processing, textiles, hair coloring, paints, and printing. Strict workplace protections can prevent much of the exposure that is believed to cause cancer.

Smoking, gender, and diet can affect the risk of developing bladder cancer.

Anything that increases your chance of getting a disease is called a risk factor. Risk factors for bladder cancer include the following:

• Smoking.
• Being exposed to certain substances at work, such as rubber, certain dyes and textiles, paint, and hairdressing supplies.
• A diet high in fried meats and fat.
• Being older, male, or white.
• Having an infection caused by a certain parasite.

• Diet: People whose diets include large amounts of fried meats and animal fats are thought to be at higher risk of bladder cancer.
  
  
• Aristolochia fangchi: This herb is used in some dietary supplements and Chinese herbal remedies. People who took this herb as part of a weight loss program had higher rates of bladder cancer and kidney failure than the general population. Scientific studies on this herb have shown that it contains chemicals that can cause cancer in rats.

These are factors you can do something about. You can stop smoking, learn to avoid workplace chemical exposures, or change your diet. You cannot do anything about the following risk factors for bladder cancer:

• Age: Seniors are at the highest risk of developing bladder cancer.
  
  
• Sex: Men are three times more likely than women to have bladder cancer.
  
  
• Race: Whites have a much higher risk of developing bladder cancer than other races.
  
  
• History of bladder cancer: If you have had bladder cancer in the past, your risk of developing another bladder cancer is higher than if you had never had bladder cancer.
  
  
• Chronic bladder inflammation: Frequent bladder infections, bladder stones, and other urinary tract problems that irritate the bladder increase the risk of developing a cancer, more commonly squamous cell carcinoma.
  
  
• Birth defects: Some people are born with a visible or invisible defect that connects their bladder with another organ in the abdomen or leaves the bladder exposed to continual infection. This increases the bladder's vulnerability to cellular abnormalities that can lead to cancer.
