INSIGHT

Most Colon Cancer Starts As Polyps

  • Colon cancer almost always begins as a polyp in the colon lining and can slowly transform into cancer over years.
  • Polyps grow inward then through bowel layers and can metastasize to liver or lungs if not removed early.
ADVICE

Use Colonoscopy To Prevent Cancer

  • Get colonoscopies even without symptoms because removing precancerous polyps prevents cancer.
  • Dr. Beth Moore removes polyps during colonoscopy, making the procedure both diagnostic and preventative.
ADVICE

Begin Screening At 45 And Prep Correctly

  • Start average-risk screening at age 45 and sooner if you have risk factors or symptoms.
  • Prep involves avoiding nuts/seeds, clear liquids day before, then split-dose laxative (one bottle afternoon, one at night) for effective cleaning.
