Can diarrhea part of colon cancer- and i added a fun thing he did?

That truly is funny... at least he didn't miss the appt, which probably would have taken a whole month to get rescheduled. My symptoms were real similar to your hubbys. I had constant diarrhea and bloated constantly. I had a colonoscopy, a sigmoid and a bunch of rectal exams as well as stool tests to check for blood in my stool. All which were negative except fissures. They were painful and caused diarrhea and painful bowels. Before my initial visit to have the colonoscopy the GI dr. told me it could be a hundered of other things besides cancer but did the colonoscopy to rule out colon cancer. It was very uncomfortable and thanfully it was over pretty fast. I think the worst part of it all was drinking that poopy medicine the night before. I still have the problem every now and then and it's a pain in the ???. I hope my answer helps a little. Hope he's feeling better soon.
