Pronunciation

Etymology

It is borrowed from Latin cancer (“a crab, a creeping ulcer, tumor, the constellation Cancer”),[2][3] a form modelled on and cognate with Greek Ancient Greek καρκίνος (karkínos), which has the same three meanings, crab, tumor and constellation.[2][3] Barnhart also compares Sanskrit karkaṭa- “crab” and karkara- “hard”,[3][4] and Etymonline takes the words to a reduplicated form of Proto-Indo-European *kar- (“hard”).[2][3] The Greek physician Galen explained the medical sense by the likeness of the swollen veins around the sore to a crab's legs.[3][5][6] Its doublet canker was the usual form for the disease until the 17th century.[5][6][3]

Earliest recorded meaning

Old English cancer, a spreading sore, malignant or not, is found about 1000 in Ælfric;[3][2] the sign of the zodiac is from about 1380, in Chaucer's translation of Boethius.[3][7]

Semantic evolution

The Old English word was displaced by the French-influenced canker[2][5] but was reintroduced in the modern medical sense, a malignant tumor, about 1600,[2] first in Holland's translation of Pliny (1601).[3][7] When canker returned to the language of medicine as cancer, canker became the word for various plant diseases.[5] The figurative sense, a spreading evil, is from 1651.[7] A crab itself was a cancer from 1562, later only in zoology.[7] A person born under the sign of Cancer is from 1894.[2][7] Since the sun is in Cancer at the summer solstice, Latin writers linked the constellation with summer heat and the south.[2] Cancer stick, “a cigarette”, is slang from 1959.[2] Cancerous is from 1563.[3]
