Could Elevated Pancreatic Enzymes And Thickened Colon Wall Indicate Neoplasia?

My husband has Elevated Pancreatic Enzymes, A Thickening in the wall of his colon, Pain that shoots from his left buttock down his left leg, is scheduled for a colonoscopy, and I am worried he has neoplasia. The physicians are beating around the bush. He cannot get right in to see people and I am worried time is of the essence. Any thoughts?
