What Is Adenocarcinoma of the Appendix?
Adenocarcinoma of the appendix is a epithelial cancer of the appendix. The term 'epithelium' refers to cells that line hollow organs and glands and those that make up the outer surface of the body. Epithelial cells help to protect or enclose organs. Some produce mucus or other secretions. Types of adenocarcinoma of the appendix include mucinous adenocarcinoma, non-mucinous adenocarcinoma, and signet cell carcinoma of the appendix (which is the rarest, involving only 4% of all the subtypes of appendix cancer).
