Overview
Colorectal cancer is the third most commonly diagnosed cancer in the world, and accounts for 8% of all cancer-related deaths annually. In the United States, the prevalence of colorectal cancer is 376.3 per 100,000 persons, and the incidence is 42.9 per 100,000 persons. The incidence of colorectal cancer is higher in males, the elderly, and in the African American race.
Epidemiology and Demographics
The epidemiology and demographics of colorectal carcinoma can be explained as follows:
Incidence
- In 2014, the incidence of colorectal cancer was estimated to be 42.9 cases per 100,000 persons in the United States[1]
- From 2001-2010, the overall incidence rates of colorectal cancer has decreased by an average of 3.4% per year[1]
- In 2014, the incidence of colorectal deaths was 5.8 per 100,000 persons in the United States.[1]
Prevalence
- In 2012, the prevalence of colorectal cancer was estimated to be 376.3 cases per 100,000 individuals in the United States[1]
Age
- The incidence of colorectal cancer increases with age.[1]
Race
- Colorectal cancer usually affects individuals of the African American race. Asian Pacific Islander individuals are less likely to develop colorectal cancer.[1]
- In 2006-2010, the colorectal cancer incidence rates among the African American race were approximately 25% higher than the Caucasian race and 50% higher than the Asian Pacific Islander race.[1]
Gender
- Men are more commonly affected by colorectal cancer than women. The male to female ratio varies with age and is approximately:[1]
- 1 to 1 - birth to 49 years
- 1 to 4 - 50 to 79 years
- 1 to 2 - 80 years and older
- Worldwide, colorectal cancer is the third most commonly diagnosed cancer when men and women are considered separately, and the second leading cause when both sexes are combined.[1]
