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.

Sessile serrated polyps and traditional serrated adenomas: These have a higher risk of being cancerous. Sessile are broad and flat polyps, while serrated polyps have a “saw-tooth” appearance.

Most sessile polyps are benign (noncancerous), but certain types, such as sessile serrated adenomas, are associated with an ...

“We need better intermediate- and long-term data on the impact of adenoma detection ... especially for polyps that are more clinically significant or for flat sessile serrated polyps, which ...
