Lung cancer is a very common type of malignancy of the respiratory system. Generally speaking for advanced lung cancer, the cost of one course of chemotherapy may be about $8,800. However, there may be some differences in the cost depending on different levels of hospitals and different regions. In addition, if patients choose imported drugs or other special treatment methods, the cost may also be high. Late stage lung cancer chemotherapy is mainly palliative symptomatic pain relief treatment, which may be more reactive and require the application of antiemetic and reaction-reducing drugs, and the hospital stay will be longer and the cost will become higher. Generally, the protocols used for advanced lung cancer are different for lung adenocarcinoma and lung squamous carcinoma depending on the type of pathology. If the treatment can be combined with targeted drugs, the effect may be better, but the cost is also higher.
