what does it mean if the colonoscopy shows you have a thickened fold with mixed polyp with both hyperplastic as well as adenomatous changes
Polyp is usually a mushroom like mass growing from the colonic wall and bulging into the colon lumen. Histological examination will probably be made and then it will be said if polyps were cancerous or not.
In diverticulosis small pouches bulge out from the colonic wall. They by themselves are not harmful but may cause constipation and may get inflammed (diverticulitis).
So, it depends on your symptoms and on what exactly will be the result of investigation of polyps.
