Etymology: "Leukoses" is the plural of "leukosis," a term built from two Greek elements. The first, "leuko-," comes from Greek "leukos," meaning "white" or "bright," the same root that gives English "leukocyte," the white blood cell whose overproduction defines these conditions. The second, "-osis," is a suffix from Greek "-ōsis," used to form nouns denoting a process or an abnormal or diseased state, as in "neurosis" or "tuberculosis." Put together, the name describes a condition characterised by an abnormal state of white cells. The plural form simply reflects that the term covers a family of related disorders rather than a single disease, so each leukosis names a distinct form of the condition.

Synonyms: leukemia, leukemia types, blood cancers
