Real-World Examples
“She said in that announcement that it had "metastasised" to her bones following a diagnosis a year-and-half-ago, meaning it was "too late" for chemotherapy.” “The relationship remained statistically significant even after the researchers accounted for well-established prognostic factors, including tumor stage, lymph node metastasis, surgical margins, chemotherapy, and nutritional status.” “In cancer research, they have been found to affect processes that include cancer metastasis and anti-tumor immune responses.” Etymology
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.
