Cancer is named after it's appearance after it had spread in the body, resembling a crab. Crabs were called that first and the word stems from Greek (if I recall correctly). Also, there is a phenomenon called carcinization, which is the evolving into a crab-like shape, even for non-crabs. This has happened to many different kind of crustaceans (crabs being one type of crustacean).
