He has never smoked and has an otherwise unremarkable medical history. He takes no medications. His vital signs are normal and the physical examination is unremarkable. A dedicated CT of the chest shows only the 5-mm left lower lobe nodule and is otherwise normal. There are no other chest images available for comparison.

5. A 62-yeаr-оld mаn with stаge III cоlоn cancer underwent a right hemicolectomy 2 years ago, removing the cecum, the ascending colon, the hepatic flexure (where the ascending colon joins the transverse colon), the first one-third of the transverse colon, and part of the terminal ileum, along with fat and lymph nodes. He received 6 months of adjuvant chemotherapy after surgery. On a recent routine follow-up visit, a serum carcinoembryonic antigen level was elevated to 43 ng/mL (upper limit of normal, 5 ng/mL). He has no other medical issues and takes no medications. On physical examination, vital signs are normal. His abdomen is soft and non-tender with no distention or masses. The liver edge is palpable just below the right costal margin and bowel sounds are normal. No lymph nodes are palpable above the clavicle or collarbone toward the hollow of the neck. Computed tomography (CT) scans of the chest, abdomen, and pelvis demonstrate a single, 1.5-cm-diameter, hypodense lesion in the right lobe of the liver. No other abnormalities are seen on the CT scan. Which of the following is the most appropriate management?
