Sessile serrated adenomas (also called sessile serrated polyps) Traditional serrated adenomas; These types of polyps are not cancer, but they are pre-cancerous (meaning that they can turn into cancer), so they need to be removed completely. Someone who has had a serrated polyp has an increased risk of later developing colon or rectal cancer.
It is believed that sessile serrated polyps may be the cause of a substantial number of “interval” colorectal cancers—ie, cancers that occur af-ter colonoscopy but before the next scheduled examination. Serrated polyps get their name from their jagged appearance on microscopy.
Only certain types of serrated polyps are precancerous. Healthcare providers classify them when they find them in order to predict their cancer risk. The four types of serrated polyps: Hyperplastic polyps. Sessile serrated lesions. Traditional serrated adenomas. Unclassified serrated adenomas. Hyperplastic polyps
Evidence suggests that up to one fifth of colorectal carcinomas develop from serrated polyps, named for their pattern of colonic crypts, and include the sessile serrated adenoma/polyp (SSA/P) that has malignant potential.
serrated adenoma or adenoma (adenomatous polyp)? These types of polyps are not cancer, but are precancerous and therefore, you have some increased risk of subsequently developing cancer of the colon.
An area of particular uncertainty is the risk in patients with sessile serrated polyps, 3 a more recently recognised precursor for colorectal cancer. Addressing these questions is increasingly urgent as efforts to prevent the disease intensify and more patients have polyps removed.
Sessile serrated adenomas are considered precancerous. This type of polyp gets its name from the sawlike appearance the serrated cells have under the microscope.
