The treatment cost of advanced lung cancer varies depending on the type of lung cancer, which leads to different treatment methods, thus the corresponding cost varies. Small cell lung cancer mainly adopts integrated treatment of radiotherapy and chemotherapy, which generally requires six courses of chemotherapy and one course of radiotherapy, and the total cost is about 100,000 RMB. Non-small cell lung cancer can be treated with chemotherapy, radiotherapy and targeted drugs, and the cost of chemotherapy and radiotherapy is about 100,000 RMB, but the cost of targeted drugs is not easy to say. At present, targeted drugs are divided into first generation, second generation and third generation. The cost of one generation is generally about RMB 6,000 a month, while the third generation of targeted drugs generally needs about RMB 50,000 a month, and the specific treatment needs to be decided by combining with the pathological type of lung cancer.
