The price of radiotherapy for esophageal cancer is the same 25 times, but it is different in different regions, different levels of hospitals, different radiotherapy machines, and different radiotherapy plans and different fields. For example, in a primary hospital, esophageal cancer may still be treated with general radiotherapy in 2 fields, in this case, the price of radiotherapy for 25 sessions is about 5000-6000 RMB. If we do mainstream intensity-modulated radiotherapy in a large general hospital or a specialized oncology hospital, assuming 5 fields, the cost of 25 sessions of radiotherapy will be about $30,000, so the difference is very big. In addition, there are more expensive radiotherapy machines, such as proton radiotherapy and radio-wave knife radiotherapy, which are even more expensive. The highest price for proton radiotherapy can go up to $280,000, so there is no way to make a generalization. In most tertiary hospitals using the mainstream radiotherapy, the cost is about $30,000 for 25 sessions.
