Screening is only recommended for people who are not experiencing symptoms that may indicate colon cancer. Symptoms can include blood in your stool, abdominal pain, change in bowel habits, or unexplained weight loss. If you are experiencing these symptoms, talk to your health care provider about a referral for diagnostic testing to determine the cause of these symptoms.

Individuals with a personal history of colon cancer, ulcerative colitis, or Crohn's disease have individual needs that cannot be met with a population approach to screening. These patients should continue to obtain care through their specialist or primary care provider.
