Adenocarcinoma

特許 権利維持 Adenocarcinoma (adeno-, "gland" and karkin(o)-, "cancerous" and -oma, "tumor") (/ˌædɨnoʊkɑrsɨˈnoʊmə/; plural adenocarcinomas or adenocarcinomata /ˌædɨnoʊkɑrsɨˈnoʊmɨtə/) is a type of cancerous tumor that can occur in several parts of the body. It is defined as neoplasia of epithelial tissue that has glandular origin, glandular characteristics, or both. Adenocarcinomas are part of the larger grouping of carcinomas. Cancers that are adenocarcinomas are often usually called by more precise terms omitting the word, where these exist. Thus invasive ductal carcinoma, the most common form of breast cancer, is adenocarcinoma but does not use the term in its name, but esophageal adenocarcinoma does, to distinguish it from the other common type of esophageal cancer, esophageal squamous cell carcinoma, which is not adenocarcinoma. Several of the most common forms of cancer are adenocarcinomas, and the various sorts of adenocarcinoma vary greatly in all their aspects, so that few useful generalizations can be made about them.
