CEA
CEA stands for carcinoembryonic antigen. CEA is a protein that is a type of "tumor marker." Tumor markers are substances that are often made by cancer cells or by normal cells in response to cancer.
A CEA test is mostly used in people who have been diagnosed with cancers that often increase CEA levels. It's most commonly used in colorectal cancer.
