Prognosis (older Greek πρόγνωσις, modern Greek πρόγνωση - literally fore-knowing, foreseeing) is a medical term denoting the doctor is prediction of how a patient is disease will progress, and whether there is chance of recovery. Since the 20th century, the word has been increasingly used in non-medical contexts as well, for example in corporate finance.
