Hello Bonnie, I agree with Colleen. I would ask your Dr. why the polyps were not removed. If he lacks the expertise to remove sessile (flat) polyps in the appendix area, maybe he can give you a referral to someone who can. I have a polyposis syndrome -Serrated Polyposis Syndrome and have yearly colonoscopies to remove any that have grown from year to year. They have ranged from 1 mm – 9 mm. Some are hyperplastic and some are sessile serrated adenomas which are pre-cancerous and need to be removed. Good Luck!
