Hello @jrsklms! So sorry about your dilemma, and let me say that it is not uncommon for GI doctors to advise colectomy for a large, flat (sessile) polyp. I have not been through this situation, but I have heard of this recommendation. However, there is a new alternative procedure that may eliminate the need for colectomy. It is called Endoscopic Mucosal Resection (EMR). It is a highly advanced technique of endoscopy which is being performed more often. I advise you to get a second opinion, with a doctor who performs the EMR procedure.
