There are few things in this world that I truly hate but cancer is right near the top. And not so much because it kills, because we all have to go sometime. But the fact that it fucks with you; It recedes just enough to give hope - then comes back to claim it's victory. That to me is the cruelest part.
Cancer means to me pincers
of the crab.
O.E. cancer "spreading sore, cancer" (also canceradl), from L. cancer "a crab," later, "malignant tumor," from Gk. karkinos, which, like the Modern English word, has three meanings: crab, tumor, and the zodiac constellation (late 14c. in English), from PIE root *qarq- "to be hard" (like the shell of a crab); cf. Skt. karkatah "crab," karkarah "hard;" and perhaps cognate with PIE root *qar-tu- "hard, strong," source of English hard. Greek physicians Hippocrates and Galen, among others, noted similarity of crabs to some tumors with swollen veins. Meaning "person born under the zodiac sign of Cancer" is from 1894. The sun being in Cancer at the summer solstice, the constellation had association in Latin writers with the south and with summer heat. Cancer stick "cigarette" is from 1959.
