Stage Migration
Stage migration describes change in the distribution of stage in a particular cancer population induced by either a change in the staging system itself or else a change in technology which allows more sensitive detection of tumor spread and therefore more sensitivity in detecting spread of disease (e.g., the use of MRI scan). Stage migration can lead to curious statistical phenomena (for example, the Will Rogers phenomenon).
