Factors That Increase Your Risk for Colon Polyps or Colorectal Cancer
Your doctor may recommend earlier or more frequent testing if you:
- Already have been diagnosed with colorectal cancer.
- Have a first-degree relative (parent, brother, sister, or child) with an adenomatous polyp or colorectal cancer.
- Are an African American.
- Have had adenomatous polyps removed from your colon. This type of polyp is more likely to turn into cancer, but the risk is still very low.
- Have inflammatory bowel disease, such as ulcerative colitis or Crohn's disease.
- Have a rare inherited polyp syndrome, such as familial adenomatous polyposis (FAP) or hereditary nonpolyposis colon cancer (HNPCC).
- Have had radiation treatments to the abdomen or pelvis.
If you have an increased risk for colon polyps, the frequency of your screening depends on your overall health, age, and combination of other risk factors. Talk with your doctor about the types and frequency of tests that will be best for you and your level of risk.
