In brief: ?Early detection tes

CT scan is not a good Test for early detection of Colon Cancer, so Colonoscopy is the preferred test because it accomplishes 2 objectives.
..detect polyps/precursors of colon cancer and remove them at the same time which eliminates the risk of Polyps changing into cancer. If you have difficulty with having Colonoscopy, then you should ask your doctor to suggest some alternative tests for checking.

In brief: CT vs. colonoscopy

Although CT can identify some colon cancers, it can certainly miss many, particularly the smaller (still potentially curable) ones.
Colonoscopy is the gold standard for identifying and sometims curing colon cancer.
