neoplasm

The word 'neoplasm' is a modern scientific term constructed directly from Greek elements to precisely describe a medical phenomenon. It combines neo- (new) with -plasm (formation, growth), creating a literal meaning of "new growth". This term was adopted into medical English in the 19th century to provide a neutral, descriptive label for abnormal tissue masses, distinguishing them from normal physiological growth. The logic is transparent: it describes the fundamental characteristic of the condition—the formation of new, often uncontrolled, cellular tissue.

Structure: neo (new) + plasm (formation, growth) - neo: From Greek neos, meaning "new". A combining form indicating newness or recent origin. - plasm: From Greek plasma, meaning "something molded or formed", from plassein, "to mold or form". A combining form denoting a formative substance or growth.
