Lung occupying metastasis of liver cancer needs to be treated by different methods according to specific conditions, and surgery, local treatment and systemic palliative treatment can be chosen. 1. Surgery: radical liver cancer surgery and local lung resection if conditions permit, supplemented by radiotherapy before and after surgery. 2. Local treatment: Cancer with organ metastasis is usually in advanced stage and only some patients have surgical indication, but if the metastasis is only isolated and the lesions are not more than 3 small lesions, local radiotherapy or radiofrequency ablation can be carried out. 3. Systemic palliative treatment: if the metastasis is diffuse and there are different degrees of distant metastasis, systemic radiotherapy and other palliative treatments are needed to improve the quality of life and prolong the survival time as much as possible. It is recommended to consult a doctor in time for targeted treatment.
