Multiple HCC of the liver is defined as the presence of more than 2 or more foci of hepatocellular hepatocellular carcinoma in the liver. Hepatocellular hepatocellular carcinoma is caused by heredity, hepatitis B or C virus infection, aflatoxins, smoking, and diabetes. It is the main subtype of primary liver cancer, accounting for 90% of cases, and is the third most common cause of death worldwide. Hepatocellular hepatocellular carcinoma has poor prognosis, high recurrence rate and intrahepatic metastasis. Hepatocellular carcinoma is often found in the early stage with insignificant symptoms and insidious onset, and is mostly found during physical examination. Once symptoms appear, it has already entered the middle or late stage of hepatocellular carcinoma, therefore, AFP and ultrasound screening can be performed to detect hepatocellular carcinoma at an early stage. Therefore, AFP and ultrasound screening can detect hepatocellular carcinoma at an early stage. If HCC is detected in screening, it is recommended to consult a doctor in time and give targeted treatment or therapy after completing the examination to clarify the cause of the disease.
