Gastric Tumor Markers And Their Role In Early Detection

Gastric tumor markers are substances that can be found in the blood and are often associated with the presence of stomach cancer. One of the most commonly used markers is CEA, which stands for carcinoembryonic antigen. Other related markers include CA 199 and CA 724. These markers are typically produced by gastric tumor cells or released as hormones and can be detected through blood tests. Each of these markers has a defined normal range, and elevated levels may suggest an increase in tumor-related activity in the gastrointestinal tract.

It is important to note that elevated levels of CEA or other markers do not always confirm cancer, but they do warrant further investigation. In clinical settings, a rise in these tumor markers often leads to additional diagnostic procedures such as endoscopy or colonoscopy. A gastroscopy, in particular, allows doctors to visually examine the esophagus, stomach lining, and upper part of the small intestine for any abnormal tissue.

If suspicious areas are found during the procedure, a biopsy is usually performed to confirm whether cancer cells are present. Even if tumor marker levels are within the normal range, it doesn't completely rule out the possibility of gastric cancer. Therefore, tumor markers are best used as a screening tool rather than a definitive diagnostic method.

Early detection remains key in improving outcomes for gastric cancer patients. Regular check-ups and awareness of changes in your body can lead to timely diagnosis and treatment. If you experience symptoms like unexplained weight loss, persistent abdominal pain, or changes in digestion, it's wise to consult a healthcare professional.

Understanding your risk factors and undergoing appropriate screenings can make a significant difference in managing your health.
