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.

Overview

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

Prevalence

  • In the United States, the age-adjusted prevalence of bladder cancer is 130.5 per 100,000 persons in 2011.[1][2]

Incidence

  • The incidence of bladder cancer is approximately 20.3 per 100,000 individuals in the United States, based on 2008-2012 data.[3][4]
  • The delay-adjusted incidence of bladder cancer in 2011 was estimated to be 20.74 per 100,000 persons in the United States.[1][5]
  • In 2011, the age-adjusted incidence of bladder cancer was 20.13 per 100,000 persons in the United States.[1]

Age

  • 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:[1][6]
    • 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.[3]

Gender

  • In the United States, the age-adjusted prevalence of bladder cancer by gender in 2011 is:[1][7]
    • 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:[1][8]
    • 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:[1][9]
    • In males: 35.18 per 100,000 persons
    • In females: 8.72 per 100,000 persons
  • Shown below is an image depicting the delay-adjusted incidence and observed incidence of bladder cancer by gender and race in the United States between 1975 and 2011. These graphs are adapted from SEER: The Surveillance, Epidemiology, and End Results Program of the National Cancer Institute.[1]

Race

  • Shown below is a table depicting the age-adjusted prevalence of bladder cancer by race in 2011 in the United States.[1]
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
  • Shown below is an image depicting the incidence of bladder cancer by race in the United States between 1975 and 2011.[1]

<figure-inline class="mw-default-size"></figure-inline>

API: Asian/Pacific Islander; AI/AN: American Indian/ Alaska Native

Developed Countries

  • The incidence of bladder cancer is higher in Western countries as compared to developing countries.[10]

Developing Countries

  • 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.[14]
