The early symptoms of liver cancer primarily manifest as localized gastrointestinal symptoms. Patients develop an aversion to greasy foods and experience a decrease in appetite. Some may feel bloating and pain in the abdomen, nausea, and distention after eating, and even pain and bloating as early symptoms. Patients become reluctant to be active, and some liver cancer patients may not exhibit many symptoms in the early stages. The precursors of liver cancer mainly present as unexplained fatigue or generalized weakness. If individuals with a family history of liver cancer experience unexplained anorexia, fatigue, and lethargy, the possibility of liver cancer should be considered.
