As liver tumors are divided into benign tumors and malignant tumors, there are differences in the symptoms and symptoms of different types of pre tumor: 1. Different conditions of liver cancer have different symptoms and characteristics: the symptoms of pre liver cancer often have no specificity, and the clinical manifestations may only have the feeling of dull pain in the liver area, or only be found in the physical examination of B ultrasound or CT. In the late stage of liver cancer, there may be pain in the right upper abdomen, abdominal distention, upper gastrointestinal bleeding, blood in stool, even rupture and bleeding of liver cancer, and even severe ascites. 2. Benign liver tumors are often unresponsive and have no specific prophase symptoms, which are often found during physical examination.
