Learned borrowing from Late Latin metastasis (“(rhetoric) rapid or sudden transition from one argument, point, or topic to another”), and from its etymons Koine Greek μετάστασις (metástasis, “(rhetoric) rapid or sudden transition from one argument, point, or topic to another”) and Ancient Greek μετάστασις (metástasis, “change; removal; (medicine) movement of disease, pain, etc., from one part of the body to another”), from μετᾰ- (metă-, prefix denoting change in condition or position) (possibly ultimately from Proto-Indo-European *meth₂) + στᾰ́σῐς (stắsĭs, “condition, state; position”) (ultimately from Proto-Indo-European *steh₂- (“to stand (up)”)), modelled after μεθιστάναι (methistánai, “to change; to remove”). By surface analysis, meta- + stasis.
In reference to the spread of cancer, a semantic loan from French métastase, whose use to refer to it was coined in 1829 by the French gynecologist Joseph Récamier (1774–1852).
The plural form metastases is a learned borrowing from Late Latin metastases.
