Liver cancer recurs 4 months after ablation, ablation, surgical treatment, targeting, chemotherapy, immunotherapy, etc. need to be considered according to the actual situation, please follow the doctor’s instruction. If the tumor is small, ablation can cover the whole and generally can inactivate the tumor completely; however, if the tumor is too large and multiple ablations need to be performed targeting multiple points, there is a possibility that there is not enough heat in the local area, which leads to the inability of necrosis, and it is still active at the time of rechecking, and there is a possibility that ablation needs to be performed again targeting the active area of the liver, in order to achieve a complete inactivation effect. If the recurrence is intrahepatic only, with no metastases to other sites, and radical resection of the recurrent lesion is still achievable, surgical treatment is the preferred option. If there is already infiltration of cancer cells in the blood, systemic treatment is needed, including chemotherapy (e.g. cisplatin, fluorouracil, etc.), targeted therapy (e.g. sorafenib, lenvatinib, etc.), immunotherapy (e.g. atelizumab), etc., which is chosen according to the patient’s own condition. The specific treatment program is related to the actual condition of the patient, and it is recommended that the patient actively follow the doctor’s instructions for treatment and medication.
