Colorectal Cancer

Colorectal cancer is cancer that occurs in the colon (large intestine) or rectum. Colorectal cancer (also called colon cancer) is the second leading cause of cancer-related death in the United States, but it can be treated successfully if detected early.

The risk of getting colorectal cancer increases with age. More than 90% of colorectal cancer cases occur in people who are age 50 or older. According to the American Cancer Society, 94% of deaths from colorectal cancer occur in people older than 50.

Colorectal cancer is the third most common type of cancer in men and women. The American Cancer Society estimates 148,810 new cases of colon and rectum cancer will be diagnosed and 49,960 deaths will result from colorectal cancer in 2008 in the United States. Missouri can expect 3,090 new cases diagnosed and 1,110 deaths from colorectal cancer in 2008.  Missouri ranks 13th in the nation for new cancer cases and 14th in the nation for colorectal cancer deaths.

Screening and Detection

Screening tests are a powerful tool in the prevention and early detection of colorectal cancer.

Screening can detect colorectal cancer in its earliest stages when treatment is most effective. Screening tests also can detect colon polyps (abnormal tissue growths), which can be removed before they turn into cancer.

If everyone age 50 or older had regular screening tests for colorectal cancer, as many as 60% of the deaths from this type of cancer could be avoided.

If you are age 50 or older, or think you may have a higher than average risk of getting colorectal cancer, talk to your doctor about getting a colorectal screening test. Free screening tests are available if you meet certain residency and income guidelines.
