You usually get a report right away. If there are any problems with polyps, they are removed immediately. They are then sent to a lab to see if the are cancerous, etc. You usually get the results back in a week or so. For most people, having polyps isn't a big deal, the vast majority are not cancerous. However if they are pre-cancerous they usually want you to come back in a year or so to make sure all is well.
