neoplasm (n.)

word-forming element meaning "new, young, recent," used in a seemingly endless number of adjectives and nouns, mostly coined since c. 1880, from Greek neos "new, young, youthful; fresh, strange; lately, just now," from PIE root *newo- (see new). In the physical sciences, caeno-, ceno- is used in the same sense. Paleo- is opposed to both.

word-forming element meaning "a growth, a development; something molded," from Greek -plasma, from plasma "something molded or created" (see plasma).
