Liver occupations are not necessarily malignant; there are also benign liver occupations. Liver occupancy means a nodule or mass on the liver that is different from normal liver tissue, without specifying the nature of the mass, and includes benign liver occupancy and malignant liver occupancy. Benign liver occupations include liver cysts, hepatic hemangiomas, and cirrhotic nodules, while malignant liver occupations include hepatocellular carcinoma and hepatic sarcoma. When benign liver occupation is small, it usually does not cause obvious symptoms, while malignant liver occupation can cause decreased appetite, jaundice, emaciation, malnutrition, ascites and other manifestations. There is no such thing as generally malignant liver occupation, and benign liver occupation is also the most common, in order to clarify the nature of liver occupation, further corresponding examination should be done, such as puncture biopsy. Patients with liver metastasis should go to the hospital in time, complete the corresponding examination, choose the appropriate examination method under the guidance of the doctor, and treat or deal with it in time, so as to avoid delaying the condition.
