Where does staging collide?

In cancer medicine, staging is the classification of how far a malignant tumour has spread through the body at diagnosis, from the local growth of the primary tumour to the involvement of lymph nodes and distant organs. The dominant framework is the TNM system (tumour, nodes, metastasis), which combines those three axes into an overall stage, usually written I through IV, that guides prognosis and treatment; Edge and Compton's 2010 account of the seventh edition of the AJCC Cancer Staging Manual describes how the system is built and periodically revised. Here the referent is the measured extent of a disease in one patient, and it has nothing to do with arranging a play on a stage, replicating a computer system for testing, or gathering supplies before a move.[1]

In theatre and opera, staging is the way a work is arranged in space and made visible for performance: where the actors stand and move (the blocking), how the set, light, and objects are composed (the mise en scene), and every choice a director makes to turn a written text into a seen and heard event. Pavis's 1998 Dictionary of the Theatre treats staging, or mise en scene, as the confrontation of the dramatic text with the concrete space and living bodies of the stage. The referent is an aesthetic and spatial arrangement of a live performance, not the extent of a disease, a test copy of a software system, or a marshalling point for goods.[2]
