What prefix is used to denote something that is "new"?

The prefix "neo-" comes from the Greek word for "new." It is commonly used in medical terminology to describe conditions, cells, or treatments that are newly developed or created. For example, "neoplasm" refers to a new growth of tissue, which can be benign or malignant. This prefix emphasizes the novelty or recent onset of the condition or concept being described.

Other prefixes present in the choices have different meanings. "Myo-" relates to muscle, "micro-" refers to something small or minute, and "meta-" typically indicates change or transformation. Thus, "neo-" is distinct in its clear association with the idea of newness.
