Lung cancer that has metastasized to the liver suggests that the condition is relatively advanced and belongs to stage IV of lung cancer, that is, advanced lung cancer. In this case, the possibility of complete cure is relatively small, but it is still treatable, so don’t give up the treatment. For liver metastases, interventional chemotherapy, microwave ablation and argon helium knife cryogenic freezing can be done to control liver metastases. Primary lung cancer foci can also be treated by applying different chemotherapy programs according to different pathological types, while chemotherapy is also effective for liver metastases. Liver metastasis of lung cancer can be better treated with targeted drugs if genetic testing is done, which can play a bigger role in prolonging the survival period.
