Although The Final, Firm Diagnose Has Not Yet Been Made,

Although the final, firm diagnose has not yet been made, it is likely to be lung cancer. I know the doctor will recommend a lobectomy. Before doing that I would like to look into stereotactic radiosurgery. This is more a matter of treatment rather than the diagnoses. How should I tell the doctor I considering another treatment and could I request all my test results from him to give to the Cyberknife provider?
