What is the difference between terminal and incurable?

Answer 1

Terminal illnesses generally mean that disease is not curable and the patient has 6 months or less to live. No terminal illnesses are curable. The best case scenario is that the disease is slowed and the patient has lives more than 6 months.

Answer 2

Terminal means there is a period of time left to live. Incurable means the disease most probably will be with you for the rest of your life and does not mean it is Terminal.
