Colorectal Cancer

Elevated Biomarkers


CA 19-9

CA 125


  • Changes in bowel habits such as diarrhea or constipation
  • Rectal bleeding or blood in the stool
  • Persistent abdominal discomforts like cramps, gas, or pain
  • Weakness or fatigue
  • Unexplained weight loss
  • Feeling that the bowel doesn’t empty completely
  • Nausea or vomiting


  • Anemia
  • Visible blood in the stool
  • Palpable mass in the abdomen

Risk Factors

  • Age 50 and over
  • Personal or family history of colorectal cancer or polyps
  • Inflammatory bowel disease (Crohn’s disease or ulcerative colitis)
  • Certain genetic syndromes (Familial Adenomatous Polyposis (FAP), Lynch syndrome)
  • Sedentary lifestyle
  • Obesity
  • Smoking
  • Heavy alcohol consumption

Other Screening Tools:

  • Colonoscopy: Typically recommended every 10 years starting at age 50.
  • Fecal occult blood test (FOBT) or fecal immunochemical test (FIT):  Recommended annually.
  • Flexible sigmoidoscopy: Recommended every 5 years along with FIT every 3
  • Virtual colonoscopy (CT colonography): Recommended every 5 years.

Next Exam(s) To Do

  • Colonoscopy: This is the gold standard for detecting colorectal cancer and is
    recommended for further evaluation if OneTest indicates elevated predictive
    risk. It allows for visualization of the entire colon and rectum, and the removal
    of any precancerous polyps.
