Etymology: Ancient Greek physicians used "tylos" for a hard swelling or callus, such as the thickened skin that forms under repeated pressure. The root appears in ancient medical writing and has survived mainly in modern clinical vocabulary. The term itself is a modern construction. Its second element, "-ectomy", comes from the Greek "ektomē", meaning "a cutting out", formed from "ek" (out) and "temnein" (to cut). Surgeons attach this suffix to a root naming the body part or growth being removed, as in appendectomy. Tylectomy thus names the excision of a lump, here applied to breast tissue.
