Colon Cancer Screening: Colonoscopy

One of the pitfalls of the FIT and multitarget DNA test (trade name Cologuard) is the inability to find polyps. A poly is a small growth on a stalk. Think of a skin tag in your colon. Some polyps are harmless. Others have malignant potential. Polyps that can turn into cancer are called adenomas. An adenoma is the middleman of cancer. As we wrap up our discussion on screening tests we will take closer look at a gold standard, the colonoscopy, which is critical for finding and removing polyps and adenomas.
