Had endometrial biopsy. doc said no cancer was found but it showed "disorganized cells". waiting for gyn call. what does disorganized mean? what do?

Not entirely normal: Unless we can see the formal pathology report, it is hard to tell exactly what it means. When cells are not entirely normal in their appearance or orderly in their location/organization, you will see such a report. It simply means to recheck them again in the future so that your doctor can keep an eye on the observed changes which can either settle down with time or rarely, progress to cancer.
