There is no such expression as “four early stages”, but there are mainly digestive symptoms such as loss of appetite and fever in early stage of liver cancer. 1. Digestive symptoms: Early liver cancer patients may have digestive symptoms such as loss of appetite, nausea, vomiting or diarrhea, which are caused by abnormal liver function or tumor secretion of abnormal substances. 2. Fever symptoms: Some patients with early stage of liver cancer may have fever for unknown reasons, which is caused by the release of pyrogen into blood circulation after tumor tissue necrosis. The fever is usually around 37.5℃～38℃, and occasionally above 39℃, which is irregular, mostly without chills, and fever in the afternoon is more common. Early symptoms of liver cancer are usually mild and often overlooked because of simple digestive discomfort and fever, so it is recommended to go to the hospital in time once you have symptoms of unexplained digestive discomfort and fever.
