Etymology
From Middle English canker, cancre, from Old English cancer (“cancer; crab”), akin to Dutch kanker, Old High German chanchar. Ultimately from Latin cancer (“a cancer”). Doublet of cancer, a later borrowing from Latin, and chancre, which came through French.
From Middle English cankren, from the noun (see above).
