A 70 year-old-man comes to the clinic for generalized fatigue. He says that he is more tired than before and has difficulty catching his breath while walking upstairs. He feels tired quickly doing his usual activity such as gardening and shopping. He does not have any symptoms of fever, change in bowel habits, abdominal pain, rectal bleeding, or weight loss. His appetite is normal. His last colonoscopy was done 10 years ago and it was normal. His blood pressure is 116/74 and heart rate is 87/min. On physical examination, his conjunctivae are pale. A routine blood test shows iron deficiency anemia with hemoglobin of 10 gm/dL. His stool is positive for occult blood. He is then sent for a colonoscopy (image is shown). What is the most likely diagnosis for the above condition?
