Can h pylori affect the lower digestive tract?

My husband found out in May that he has h. Pylori. He was having a burning in his lower digestive tract, and frequent bowel movements. We tried mastic gum and a change in diet to help rather than the triple therapy. For as long as he stuck with the diet (no more than a month) he felt better, but he didn't stick with it long and he is symptomatic again.
He is doing the triple therapy right now, and today he went to see a gastric specialist. The doctor said h. Pylori should be felt in the stomach, not low down, so he is ordering a scope and a colonoscopy. I am wondering how worried I should be about finding cancer or something unrelated to the h pylori?
We are planning to change his diet again following the triple therapy, as well as supplement with probiotics.
