Generally, the value of alpha-fetoprotein in benign liver tumors is 200~400μg/L, but the specific conditions of different patients are different, and this value is not fixed. Alpha-fetoprotein is a non-specific marker, and its normal level in serum is <25μg/L. Its increase is common in liver cancer, testicular cancer, ovarian tumor, malignant teratoma, pancreatic cancer, acute and chronic hepatitis, cirrhosis and other diseases. In addition, pregnant women also have physiologic elevations during pregnancy, so it is not specific. In general, patients with benign liver tumors may have a value of alpha-fetoprotein between 200 and 400 μg/L, but this value is not fixed, and if the patient’s condition is mild, the increase may not be obvious. Therefore, patients usually need to undergo other tests to further clarify the diagnosis. It is recommended that the patient consult a professional doctor with the test results, and the doctor will combine other clinical symptoms and auxiliary tests to confirm the diagnosis, a single increased value of alpha-fetoprotein can not determine what kind of disease.
