[|AI|]  Hi, Thanks for writing in. A cyst in the chest with a history of untreated lung cancer is to be evaluated in detail. It means he has to get FNAC or biopsy of the cyst done with CT scan of the lung to assess the cancer. If there was problem in arranging for chemotherapy then you might have approached government cancer research institutes. In these hospitals, there are chemotherapy trials which are to study the effect of newer medicines on cancer. Many patients are registered to get medicines free of cost for registering in Chat Doctor.  Even now you can approach government cancer hospitals and know if any such trial is taking place for lung cancer patients.
