Paper Title
CEA Tumor Relationship in Patients with Colorectal Carcinoma

Abstract
Cancer is the name given to abnormal and unregulated growth of cells which multiply in an uncontrolled and unabated way and, in some cases, to metastasize. For the evolution of a tumor from normal to a fully malignant tumor, multiple internally additive mutational events are required. In terms of molecular genetics, colon cancer is probably one of the most multivalent cancers. CEA is now one of the most widely used tumor markers worldwide and certainly the most frequently used marker in colorectal cancer. Keywords - Colorectal Cancer, Carcinoembryonic Antigen.
