Overview
Worldwide, bladder cancer is the 7th most common type of cancer in males and the 17th most common cancer in females.[1] Bladder cancer is more common in developed countries than in developing countries.[2] In the United States, bladder cancer is the fourth most common type of cancer in men and the ninth most common cancer in women. More than 47,000 men and 16,000 women are diagnosed with bladder cancer each year.[3] The incidence of bladder cancer is higher in men than in women possibly because the androgen receptors might contribute to this disease and they are more active in men.[4] While transitional cell carcinoma is the major type of bladder cancer in Western countries, squamous cell carcinoma accounts for a large number of cases of bladder cancer in African areas endemic for schistosomiasis.[5]
Epidemiology and Demographics
Prevalence
- In the United States, the age-adjusted prevalence of bladder cancer is 130.5 in 2011.[6]
Incidence
- The delay-adjusted incidence of bladder cancer in 2011 was estimated to be 20.74 per 100,000 persons in the United States.[6]
- In 2011, the age-adjusted incidence of bladder cancer was 20.13 per 100,000 persons in the United States.[6]
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:[6]
- Under 65 years: 5.4 per 100,000
- 65 and over: 124.7 per 100,000
Gender
- In the United States, the age-adjusted prevalence of bladder cancer by gender in 2011 is:[6]
- 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:[6]
- 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:[6]
- 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.[6]
Race
- Shown below is a table depicting the age-adjusted prevalence of bladder cancer by race in 2011 in the United States.[6]
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.[6]
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.[2]
- Transitional cell carcinoma accounts for the majority of bladder cancer in the developed world.[7]
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.[5]
- Among patients with bladder cancer in Egypt, squamous cell carcinoma is present in approximately 60% of the cases.[7]
- 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.[8]
