met n. cancer that has spread beyond its point of origin. Editorial Note: The plural form, mets, is sometimes used in the singular, perhaps because of a mistaken reinterpretation of mets as a clipping of the singular metastasis. Etymological Note: Clipping of metastasis ‘a change in a location (in a body) of a disease; a disease that has made such a change’ or metastases, the plural form. (source: Double-Tongued Dictionary)
