You need to switch Doctors. It is inexcusable for him to say that to you. My husband's oncologist will not be specific about life expectancy. He said "our patients continue to surprise us every day" so there is no way we can give a specific amount of time. We are 10 months out from his diagnosis of stage IIIa squamous cell lung cancer and he is now in remission. Recent bronchoscopy and 8 biopsies show no cancer. Keep the faith and do insist on changing Doctors. Find one with a personality.
