The details

According to Dr. Lee, average-risk adults should begin regular colon cancer screening at age 45. The recommended screening tests include colonoscopies every 10 years, as well as stool-based tests like FIT or Cologuard annually. She also advised patients to be well-hydrated, avoid certain medications, and follow a clear liquid diet the day before a colonoscopy to ensure the best results.
