Neoplasm

/ˈniːoʊplæzəm/noun

An abnormal growth of new tissue, benign or malignant.

The Greek roots

νέος

+
πλάσμα
plásma
something moulded

Literally: new formation

The story of the word

πλάσμα comes from πλάσσω, the potter's verb for working clay, which also stands behind plaster and plastic. Nineteenth-century pathologists adopted neoplasm precisely because it claims less than tumour or cancer: it names an uncontrolled new growth and withholds judgement on whether it will invade anything. A wart and a sarcoma are both neoplasms, and the word is doing careful work when a doctor chooses it.
