In medicine the term “stage” is used to refer to the progression of a disease process. For instance, if diagnosed early, a person’s cancer diagnosis might be in only stage 1. If the early stage cancer does not respond to treatment it will progress through stages 2, 3, and 4 with four normally indicating the final and eventually fatal stage of the disease.
