'pancreas-related' is a compound built from 'pancreas' and the adjective-forming element 'related'. 'Pancreas' originates from Greek, specifically the word 'pankreas', where the prefix 'pan-' meant 'all' and 'kreas' meant 'flesh'. 'Related' comes from the verb 'relate', ultimately from Latin 'relatus' (past participle of 'referre'), adopted into English via Old French/Medieval Latin.

'pancreas' came into English via New Latin from Greek 'pankreas'; 'related' developed from Latin 'relatus' through Old French/Anglo-Norman forms and Middle English 'relaten', and the compound 'pancreas-related' is a modern English formation combining the organ name and a common adjectival element.

Initially, 'pancreas' (Greek 'pankreas') literally referred to 'all flesh' but came to denote the anatomical organ 'pancreas'. 'Related' originally had senses tied to 'having been brought back' or 'reported' in Latin roots, and later shifted to mean 'connected' or 'having a relation to'; combined, the modern compound means 'having a connection to the pancreas'.
