Whether you need chemotherapy or radiotherapy after surgery, it depends on the state of your lymoh nodes after surgery. The size of the tumor and moleculur analysis. So it is difficult to tell you whether you need chemotherapy or radiotherapy right now. You need to give me all your reports,including the relevant parts I just mentioned, so that I can tell you whether you need chemotherapy or not. Some patients do not need chemotherapy or radiotherapy, but it depends on the patient's condition.
