Colorectal Cancer Gene Stool Test – Screening for Bowel Cancer Risk through Stool Samples
Conditions for Undergoing the Test
✅ Who should undergo the test
Stool DNA testing is recommended for adults who:
- Are 45 years or older
- Have average risk for colorectal cancer (no high-risk hereditary syndrome).
- Have no current symptoms suggesting colorectal cancer (e.g., rectal bleeding, unexplained iron-deficiency anemia, significant unexplained weight loss).
- Are able and willing to undergo a colonoscopy if the stool DNA test is positive.
- Prefer a non-invasive screening method between colonoscopies.
❌ Who should not undergo the test
Stool DNA testing is not recommended for individuals who:
- Have a personal history of colorectal cancer, advanced adenomas, or high-risk polyps.
- Have inflammatory bowel disease (ulcerative colitis or Crohn’s disease involving the colon).
- Have a strong family history or known inherited colorectal cancer syndrome (e.g., Lynch syndrome, familial adenomatous polyposis).
- Currently have symptoms suggestive of colorectal cancer such as rectal bleeding, unexplained anemia, persistent abdominal pain, or significant weight loss.
- Had a positive stool DNA test
- Are unable or unwilling to undergo follow-up colonoscopy if the test result is positive.
Notes
- Stool DNA testing is a test that looks for abnormal DNA from colon cancer or polyps.
- Recommended for average-risk adults ≥45 years old.
- Follow-up: A positive stool DNA test MUST be followed by a diagnostic colonoscopy.
What is this screening?
- This test detects genetic alterations characteristic of colorectal cancer cells (SDC2 Methylation). It is an innovative and effective screening method that helps reduce the anxiety associated with colonoscopy.
