I Am Scheduled Monday For A Colonoscopy. Until Yesterday, I

I am scheduled Monday for a colonoscopy. Until yesterday, I had went over a week without a bm and even before had a lot of abdominal pain. Thanks to miralax, I was finally able to start going again but my stools have been long, stringy, and have some mucus. With the history of colon cancer along with the fact I already had numerous polyps removed in 2009, I am worried they are going to be telling me I have colon cancer. Is this a pretty fair assumption
