The Carcinoembryonic Antigen (CEA) Test is a blood test measuring the level of CEA, a protein that may be elevated in certain types of cancer, most commonly colorectal cancer. This test helps in monitoring cancer treatment effectiveness and detecting recurrence after surgery or chemotherapy. Elevated CEA levels can also be seen in smokers or patients with benign conditions such as inflammation, limiting its use as a sole diagnostic tool. Regular CEA testing allows oncologists to track the tumor marker trend and adjust treatments accordingly. Besides colorectal cancer, CEA testing may assist in managing other cancers like pancreatic, lung, breast, and ovarian cancer. It is typically used as part of a broader diagnostic and management plan alongside imaging and clinical assessment. Read less
