Re: Difference between Flex Sig. and Colonoscopy?
A flex sigmoid only examines the 1st 1/3rd of your colon and is often done without sedation. A colon however examines the entire colon to the terminal ileum and your are given sedation for this procedure. I would suggest doing the the colon, because cancer can occur anywhere in the colon, you are being cleaned out totally and you will at least be kept comfortable with the colonoscopy.
