between Gemini and Leo.
3. (Med.) Formerly, any malignant growth, esp. one attended with great pain and ulceration, with cachexia
and progressive emaciation. It was so called, perhaps, from the great veins which surround it, compared
by the ancients to the claws of a crab. The term is now restricted to such a growth made up of aggregations
of epithelial cells, either without support or embedded in the meshes of a trabecular framework.
Four kinds of cancers are recognized: (1) Epithelial cancer, or Epithelioma, in which there is no trabecular
framework. See Epithelioma. (2) Scirrhous cancer, or Hard cancer, in which the framework predominates,
and the tumor is of hard consistence and slow growth. (3) Encephaloid, Medullary, or Soft cancer, in
which the cellular element predominates, and the tumor is soft, grows rapidy, and often ulcerates. (4)
Colloid cancer, in which the cancerous structure becomes gelatinous. The last three varieties are also
called carcinoma.
Cancer cells, cells once believed to be peculiar to cancers, but now know to be epithelial cells differing
in no respect from those found elsewhere in the body, and distinguished only by peculiarity of location
and grouping. — Cancer root (Bot.), the name of several low plants, mostly parasitic on roots, as the
beech drops, the squawroot, etc. — Tropic of Cancer. See Tropic.
Cancerate
(Can"cer*ate) v. i. [imp. & p. p. Cancerated.] [LL. canceratus eaten by a cancer. See
Cancer.] To grow into a cancer; to become cancerous. Boyle.
Canceration
(Can`cer*a"tion) n. The act or state of becoming cancerous or growing into a cancer.
