Best of luck. I will say that a year ago I had some similar symptoms to you - rectal bleeding (on the tissue though, no blood in the actual stool), gas and trapped wind, some cramps and on-and-off loose stools. The specialist told me that as I was only 40, I'd be "the unluckiest person in the world" if it turned out to be cancer. 

It turned out to be hemorrhoids, probably combined with the stress of the whole thing and some coincidences.

I had my colonoscopy today and it went a lot better than I thought. Drinking the Moviprep was definitely the worst part about the whole thing. 
 

Anyway no cancer was found however I have inflamed, swollen and red colon. Suspected IBD 26 biopsies taken- They think chrones.

I'm so pleased that no cancer was found! Anything else should be manageable. Best of luck to you going forward! X
