The prevalence of bladder cancer is approximately 130.5 per 100,000 individuals in the United States. The incidence of bladder cancer is approximately 20.3 per 100,000 individuals in the United States. The incidence of bladder cancer increases with age; the median age at diagnosis is 73 years. Males are more commonly affected with bladder cancer than females. Bladder cancer usually affects individuals of the white race. African American, Asian, and Hispanic individuals are less likely to develop bladder cancer.
Epidemiology and Demographics
- In the United States, the age-adjusted prevalence of bladder cancer is 130.5 per 100,000 persons in 2011.
- The incidence of bladder cancer is approximately 20.3 per 100,000 individuals in the United States, based on 2008-2012 data.
- The delay-adjusted incidence of bladder cancer in 2011 was estimated to be 20.74 per 100,000 persons in the United States.
- In 2011, the age-adjusted incidence of bladder cancer was 20.13 per 100,000 persons in the United States.
- While the overall age-adjusted incidence of bladder cancer in the United States between 2007 and 2011 is 20.5 per 100,000, the age-adjusted incidence of bladder cancer by age category is:
- Under 65 years: 5.4 per 100,000
- 65 and over: 124.7 per 100,000
- The incidence of bladder cancer increases with age; the median age at diagnosis is 73 years.
- In the United States, the age-adjusted prevalence of bladder cancer by gender in 2011 is:
- In males: 228.9 per 100,000
- In females: 56.6 per 100,000
- In the United States, the delay-adjusted incidence of bladder cancer by gender in 2011 is:
- In males: 36.24 per 100,000 persons
- In females: 8.98 per 100,000 persons
- In the United States, the age-adjusted incidence of bladder cancer by gender on 2011 is:
- In males: 35.18 per 100,000 persons
- In females: 8.72 per 100,000 persons

- Shown below is a table depicting the age-adjusted prevalence of bladder cancer by race in 2011 in the United States.
|All Races||White||Black||Asian/Pacific Islander||Hispanic|
|Age-adjusted prevalence||130.5 per 100,000||148.2 per 100,000||62.9 per 100,000||58.7 per 100,000||64.4 per 100,000|

- The incidence of bladder cancer is higher in Western countries as compared to developing countries.
- Squamous cell carcinoma accounts for a large number of bladder cancer cases in African countries endemic for schistosomiasis, such as Egypt, Uganda, Senegal, Sudan, and Kenya.
- Among patients with bladder cancer in Egypt, squamous cell carcinoma is present in approximately 60% of the cases.
- In the late 1980's and early 1990's, approximately one third of cancer cases in Egypt were cases of bladder cancer. Given the improved treatment of schistosomiasis in Egypt, the incidence of bladder cancer has been decreasing.
