The cause of death from liver cancer is often cirrhosis with hepatic coma, where the patient appears 2-3 days ago with behavioral changes, disorientation, followed by a superficial coma and then a deep coma, which eventually leads to death. There are also some cases of abdominal hemorrhage due to rupture of liver cancer, which leads to hypovolemic shock and eventually death, but they are relatively rare. The most common cause of liver cancer is overconsumption caused by cancer, which can lead to systemic failure, water-electrolyte disorder, and low protein, low potassium, low chlorine, etc. The patient will be in a trance, and finally will have respiratory failure, which will eventually lead to death.
