The cost of radiation therapy for lung cancer varies depending on the means of treatment. The original lung cancer is treated by radiotherapy through X-ray, and the cost is usually several thousand dollars. The cost of general conformal radiotherapy, through radiotherapy means of X-blade and gas pedal, usually costs $15-20,000. The cost through general conformal radiotherapy with intensity modulated means is about $40,000-50,000. At present, there are better means of proton therapy, but the cost is higher, about $278,000 for individual areas, for patients with better financial conditions.
