BIOMARKERS TESTING GUIDE FOR PATIENTS

 If you or a loved one has been diagnosed with gastric (stomach) cancer, you may have heard your healthcare team mention something called “biomarker testing.” This guide is here to help you understand what that means—and why it matters.

Biomarkers are unique characteristics found in your cancer cells, such as genes, proteins, or other molecules. Testing for these biomarkers can give your doctors important information about your specific cancer type, helping them choose treatments that are most likely to work for you.

No two cancers are exactly the same, and personalized treatment based on biomarker testing is a powerful step forward in cancer care. Whether you’re just beginning your treatment journey or exploring new options, understanding biomarker testing can help you make informed decisions about your care.

Understand when your biomarker test should be done and which biomarkers are important to test for.
