How to use prognosis

Prognosis is used formally in medical contexts to describe a doctor's informed judgment about disease progression and recovery prospects, but it also extends to general predictions about future development in business, economics, or social trends. It carries an air of professional expertise and is often used when the outlook is uncertain or requires careful evaluation. It differs from diagnosis, which identifies a condition rather than predicting its course.
