Help with a case...

Come practice your diagnostic skillz! I have a case that seemed super boring at first but now I'm wondering if there's something I'm just not seeing... 66 y/o male with a history of abdominal discomfort, increasing reliance on laxatives to maintain regular bowel movements. Smoked for several years but quit over 30 years ago. Only family history is breast cancer in mother, sister. Likes to travel, recently returned from a cruise and blames food for his symptoms. Unremarkable physical except... Help with a case...
