It is possible that hyperplastic polyps, SSA/Ps and TSAs, are divergent pathways from inception. Figure 5. Typical appearance of a sessile serrated adenoma/polyp in the ascending colon.

Changes to DNA can affect oncogenes and tumor suppressor genes, resulting in multiple gene changes that may lead to colon cancer. Polyps are growths that form on the inside of the colon.

Eight endoscopists were then invited to predict the histology (each endoscopist 100 videos, 800 video assessments in all). Polyps were classified into types 1–3 (hyperplastic) and type 4 (adenoma).
