Over the last 3-4 days my crap has been really flat, and I've only piece of crap too..?

Is it colon cancer?

Hopefully it's just my Ocd and gad doing this to me.

I have been to a doctor before on this, but he just didn't pay much attention to this fear. But can a doc that gives physicals know that it isn't colon cancer?
