It is unscientific to say that the pain in three places of liver cancer should be alerted. As the symptoms of early liver cancer are atypical, it is difficult to make differential diagnosis through the pure pain site, so it is necessary to consult doctor in time and improve relevant examination to make a clear diagnosis. Early clinical manifestation of liver cancer is not obvious, usually there is no symptom or atypical symptom, and when patients feel unwell and go to the hospital, liver cancer has already developed to middle or late stage, and typical clinical manifestations of liver cancer mainly include pain in liver area. Typical clinical manifestations of liver cancer include pain in the liver area, which is a persistent hidden pain in the right upper abdomen or middle upper abdomen, and digestive symptoms, such as decreased appetite, abdominal distension, abdominal pain, and recent weight loss. The early stage of liver cancer is insidious, so for people with high risk of liver cancer, they need to have regular medical checkups, and should consult the doctor in time when they feel unwell and have a complete checkup.
