I have no real factors so my expection for this screning colonoscopy is this will just set the baseline for the future. I agree on early detection. I am glad your brother is reaching the end of a long process. There are 2 dogs,Heidi, my 12 yo GS mix and Sable, the 4 yo Sheltie. Heidi came from the local humane society when she was 2 and Sable came when she was 18 months from friends that felt she would do better in another home.
