Generally speaking, hepatocellular adenomas do not exhibit elevated levels of carcinoembryonic antigen (CEA). Regarding hepatocellular adenomas, they are benign liver lesions and typically do not cause any noticeable symptoms in patients. They are most often discovered during ultrasound examinations. Patients with larger hepatocellular adenomas may experience pain in the liver area, and there is also a possibility of rupture and bleeding. Therefore, early surgical intervention is advisable, as surgery can yield excellent treatment outcomes. However, generally, patients with hepatocellular adenomas do not exhibit an increase in CEA. Elevated tumor markers and increased CEA are found in patients with malignant liver tumors.
