Colon cancer is the third most commonly diagnosed cancer and the second leading cause of cancer death in men and women combined in the United States. The American Cancer Society estimates that this year 95,520 people will be diagnosed with colon cancer, 39,910 will be diagnosed with rectal cancer, and 50,260 will die from this disease.
On average, the lifetime risk of developing colon cancer is about one in 23 for men and women combined (4.5%), however, this varies widely according to individual risk factors.
About 71% of cases arise in the colon and about 29% in the rectum.
With regular screening, colon cancer can be found early, when treatment is most effective. In many cases, screening can prevent colon cancer by finding and removing polyps before they become cancer. And if cancer is present, earlier detection means a chance at a longer life. Generally, the more advanced colon cancer is at detection, the lower the five-year survival rates are.
Colon Cancer Survival Rates
- The five-year survival rate for colon cancer found at the local stage is 90%.
- The five-year survival rate for colon cancer found at the regional stage is 71%.
- The five-year survival rate for colon cancer found at the distant stage is 14%.
Stage at Diagnosis
According to the American Cancer Society:
- 39% of CRC patients are diagnosed with localized-stage disease
- 35% of CRC patients are diagnosed with regional- stage disease
- 21% of CRC patients are diagnosed with distant- stage disease
Colon Cancer and Age
- The median age at diagnosis for colon cancer is 68 in men and 72 in women; for rectal cancer it is 63 years of age in both men and women.
- As a result of rising CRC incidence rates in younger age groups coincident with declining rates in older age groups, the proportion of cases diagnosed in individuals younger than age 50 increased from 6% in 1990 to 11% in 2013.16 Most of these cases (72%) occur in people who are in their 40s.
Colon Cancer and Ethnicity and Race
- CRC incidence and mortality rates are highest in African Americans.
- During 2009-2013, CRC incidence rates in blacks were about 20% higher than whites CRC death rates in blacks are 40% higher than that of whites.
Your family history, ethnicity and race can put you at a higher risk for colon cancer. Read more about who should be screened and when.
Colon Cancer and Family History
- People with a first-degree relative (parent, sibling, or children) who has colon cancer are between two and three times the risk of developing the cancer than those without a family history.
