Ask
Hello doctor! I just tested with CA 72-4: 17.58H (8.2U/mL). Currently, I also have digestive problems, so I often have loose, thick, and thick stools for a long time. So the doctor asked me if I had a CA 72-4: 17.58H (8.2U/mL) test, if I had loose, thick stools for a long time, did I have stomach or colon disease? Looking forward to your help and sorry for bothering you. Thank you sincerely!

Hello! For the early diagnosis of cancer, several tumor biomarkers (cancer markers) have been widely used to improve the sensitivity and specificity of diagnosis. In particular, markers used to diagnose gastric and colorectal cancer are often used such as CEA, CA19-9, CA 72-4 and CA 125 tests. However, to increase the sensitivity and specificity, it is necessary to combine these tests. marker because each marker has low sensitivity and specificity, as well as the result of many different types of cancer. You have a high CA 72-4 test, which is a marker for the diagnosis of stomach diseases such as stomach, ovarian, colorectal and some other gastrointestinal cancers.
So in order to correctly answer the test with CA 72-4: 17.58H (8.2U/mL), do you have persistent loose, viscous stools with stomach or colon disease? Then you should go to a medical facility or hospital under Vinmec Health System to be examined, diagnosed and determined to have an effective treatment plan.
Thank you for your trust and concern to Vinmec. We hope to meet you in the near future for a more in-depth consultation. Best regards!
