With an alpha-fetoprotein of 870, it is more likely that the intrahepatic occupancy is hepatocellular carcinoma. The diagnostic criteria for hepatocellular carcinoma are one type of imaging evidence and an alpha-fetoprotein >400ng/mL, or two types of imaging evidence, or a positive pathology. A fetoprotein of 870ng/mL and liver occupation is more likely to be hepatocellular carcinoma, and if there is one imaging evidence of hepatic occupation at this time, pathologic examination can confirm the diagnosis of hepatocellular carcinoma. In addition, there may also exist some special cases, such as liver occupation is liver cyst or liver hemangioma, and elevated alpha-fetoprotein is due to cirrhosis, testicular cancer, stomach cancer, etc., but the possibility of this case is lower. If you find elevated alpha-fetoprotein and liver occupation, you need to consult a doctor in time, complete the relevant examination, make a clear diagnosis and treat it positively, so as to avoid delaying your condition.
