There is no such thing as “benign liver cancer”, it should be a benign tumor of the liver. If a benign tumor does not turn into malignant liver cancer, it does not affect the normal life expectancy. Due to the influence of various environmental and self-factors, benign tumors turn into malignant liver cancer, and the five-year survival rate is about 50%-60%. Early asymptomatic benign tumors such as hepatic hemangioma and hepatic cysts over a certain range can be cured by surgical resection, and the results of regular follow-up and periodic review after resection will not affect the life expectancy under normal circumstances. If benign tumors become malignant, such as hepatic adenoma, the five-year survival rate is about 50%-60% after treatment. Benign tumors usually do not affect life expectancy when appropriate treatment is chosen. Therefore, they need to be treated aggressively to prevent them from progressing to malignant tumors.
