In her opinion as a trained medical professional, my symptoms do not point to cancer. So we're going to eliminate all the other possible causes first.
So they are going to wait and rule out cancer last. I guess if your family has no history of intestinal cancer, then ok. When my dad was my age he had polyps in his intestine, so they wanted to make sure in my case. Turns out I did have a coupe of small, but non-cancerous polyps that they removed during the colonoscopy.
Oh, and btw this is informational:

Also, this person was a medical doctor right? How you parsed 'trained medical professional' seems to put that into question.
