About Colorectal Cancer

Southeast Gastroenterology recommends everyone obtain a colonoscopy by age 50. Individuals, under age 50, who have a family history of colon cancer or other risk factors, should have a colonoscopy.

What You Need to Know

  • Colorectal cancer is deadly. Among cancers, only lung cancer kills more Americans each year than this largely preventable disease.
  • Colorectal cancer does not discriminate. This disease affects men and women equally. Those diagnosed with the disease often experience no noticeable symptoms.
  • The good news is that if everyone, aged 50 or older, underwent regular colorectal screenings, at least 60 percent of deaths from this cancer could be avoided.

Colon Cancer Risk Factors

Colon Cancer Screening

If you have any of these risk factors, call Southeast Gastroenterology at 573-331-7910 to inquire about having a screening colonoscopy.

The following factors indicate an elevated risk for colon cancer:
  • Are you over the age of 50?
  • Do you have a family history of colon cancer?
  • Do you have a family member with a history of colon polyps?
  • Do you have a change in bowel habit?
  • Do you have (or have you ever had) rectal bleeding?
