Is it possible for CEA, C19-9, Abdominal Echo and FOB examinations to detect hemorrhoids, polyps and Colon Caner? Thank you!

No perfect tests!! Some of these tests(CEA) are only useful for far advanced Cancers(not helpful for early detection of polyps or colon cancer. CEA and CA 19-9 are tumor markers, they are useless for most cases of early cancer. Abdominal ECHO has limited usefulness to detect fluid and certain cystic lesions, not useful for Colon Cancer. The best test for checking colon for polyps and colon cancer is Colonoscopy.
