Liver malignant tumors are very common among the malignant tumors of digestive system. The treatment effect of liver malignant tumors may not be too good, especially in the middle and late stage of liver cancer, the survival period may be about three months to six months, or less than three months. If the liver malignant tumor is relatively early, it depends on the treatment. If it can be radically treated with surgery and postoperative treatment such as microwave ablation and intervention, it is possible to survive for a longer period of time, such as more than one year, two years or even longer, but it is rare to see more than five or ten years. The main symptoms of liver malignant tumor in early stage may be abdominal distension, abdominal pain, jaundice, and some may be accompanied by diarrhea and other symptoms. The clinical diagnosis of hepatocellular carcinoma can be made through enhanced CT of liver, combined with tumor indicator of elevated alpha-fetoprotein greater than 400μg/L for one month, and the diagnosis must be confirmed by liver aspiration for pathological examination.
