Tu"mor (?), n. [L., fr. tumere to swell: cf. F. tumer. See Tumid.]
1. Med.
A morbid swelling, prominence, or growth, on any part of the body; especially, a growth produced by deposition of new tissue; a neoplasm.
2.
Affected pomp; bombast; swelling words or expressions; false magnificence or sublimity.
[R.]
Better, however, to be a flippant, than, by a revolting form of tumor and perplexity, to lead men into habits of intellect such as result from the modern vice of English style.
De Quincey.
Encysted tumor, a tumor which is inclosed in a membrane called a cyst, connected with the surrounding parts by the neighboring cellular substance. -- Fatty tumor. See under Fatty. -- Innocent tumor, or Benign tumor, one which does not of itself threaten life, and does not usually tend to recur after extirpation. -- Malignant tumor, a tumor which tends continually to spread, to become generalized in different parts of the body, and to recur after extirpation, and which, if left to itself, causes death.
