Colon Cancer Screening — Patient Information

A clear guide for Valley Gastroenterology patients.

Why screening matters

Colorectal cancer often starts as precancerous polyps that can be found and removed before they turn into cancer. Screening saves lives.

Who should be screened?

  • Average risk: Start at age 45 and continue through 75.
  • Ages 76–85: Individualized decision based on overall health and prior screening.
  • Higher‑risk groups (start earlier/more often):
  • First‑degree relative with colorectal cancer or advanced polyps
  • Personal history of polyps or colorectal cancer
  • Inflammatory bowel disease (ulcerative colitis, Crohn’s colitis)
  • Certain hereditary syndromes (e.g., Lynch, FAP)

If you have rectal bleeding, iron‑deficiency anemia, unexplained weight loss, persistent change in bowel habits, or abdominal pain, you may need a diagnostic colonoscopy regardless of age.

Screening options (at a glance)

Colonoscopy (every 10 years if normal)

  • Examines the entire colon and rectum; removes polyps during the same visit
  • Requires bowel prep and a driver

FIT stool test (every year)

  • At‑home test for hidden blood; positive test requires colonoscopy

Stool DNA test (every 3 years)

  • Higher sensitivity than FIT; positive test requires colonoscopy

CT colonography (every 5 years)

  • Imaging test; polyps still require colonoscopy for removal

For most patients, COLONOSCOPY IS PREFERRED because it both detects and treats polyps in one step.

What to expect with colonoscopy (summary)

  • Prep: Usually a split‑dose bowel prep the day before and morning of your procedure (clear liquids; avoid red/purple). We’ll give exact written instructions.
  • Day‑of: 2–3 hours total (check‑in, procedure, recovery). You’ll have sedation for comfort and need a driver.
  • Results: Preliminary findings the same day; pathology (if biopsies) in 7–14 days via phone/portal.

Safety & risks

Screening tests are safe. With colonoscopy, uncommon risks include bleeding, perforation, reactions to sedation, and missed lesions. We review your individual risks and obtain informed consent.

Insurance & cost

Most plans cover screening starting at age 45. If a polyp is removed or the exam is done for symptoms, your benefits may differ. Our team will verify coverage and explain any expected costs.

Alaska‑specific travel note

We monitor Mat‑Su weather and road conditions. If travel is unsafe, we’ll reschedule without penalty and prioritize your next available slot.

Quick FAQs

How often do I need colonoscopy if it’s normal? Typically every 7–10 years depending on exam quality and your risk.

What if I’ve had polyps before? Follow‑up intervals vary by polyp type/size/number—often 3–7 years. We’ll advise your exact timing.

Do GLP‑1 or blood thinner meds change my prep? Often yes. Do not stop medications on your own—we’ll give a safe plan.
