Colonoscopy Results

I have had "mild" crohns for 8 years. Mostly lower abdominal pain and when I do have a flare its 3 or four trips to the bathroom in the morning then it stops for the day and the next day it could be the same...may last for a few weeks then its gone for a few months. I had a CT Enterography done a year and a half ago and it showed some mucosal thickening up to 13 mm in thickness involving the jejenum small bowel loops and said it does not appear to be inflamed. GI thinks it is mor IBS related. This winter from Nov to March I had abdominal pain again (seems seasonal to me) and the morning bathroom issues again a few times so he suggested I go for a colonoscopy. I had it yesterday. No sign of chrons at this time. No scarring. I realize the chrons will come back at some time but GI said to keep taking the Pentasa and thinks my issues are still IBS and I will take Librax for it. The colonoscopy did show excavated lesions - multiple non-bleeding diverticula seen in the sigmoid colon and the recommendation on the paper work was to await pathology results. I was kind of "loopy" when talking to the GI so I can't really remember what he said about it. I am not sure if I should be concerned about the diverticula? Why would they do pathology tests on that? Another thing now to stress about? Any advise would be great as I will not be seeing the GI for a while....health permitting. Thanks.

So what would they be looking for...cancer? Now I am really nervous. Since the GI didn't seem concerned when he talked to me I thought everything was basically OK. I would have thought if he was suspecting something along the lines of cancer he would have called my wife in and explained more in detail. Now I am going to be a nervous reck until the report comes back!!
