@阿丹: I found that the tumor marker CA199 exceeded the standard a little bit during my physical examination, and it was said on the Internet that it was closely related to pancreatic cancer.
The doctor answers the doubts. Don't panic just yet. Although CA199 is widely used in the screening of gastrointestinal tumors, especially pancreatic cancer, this abnormal result alone cannot diagnose pancreatic cancer.
Because CA199 is a non-specific tumor marker, it means that this elevated indicator alone cannot be determined to be a tumor, let alone malignant.
Many benign, non-neoplastic diseases, such as pancreatitis, hepatitis, inflammation of the biliary system, type 2 diabetes, etc., can cause CA199 abnormalities.
Factors such as menstruation or pregnancy, long-term smoking or alcohol consumption in women may also cause CA199 to fluctuate.
However, the following should be taken into account:
Significant elevation of a single test (more than 2 times the normal range);
The re-examination found that the value continued to rise;
Other results are found to be abnormal at the same time as physical examination, or accompanied by physical discomfort;
Have a family history of tumors.
In fact, not only CA199, many tumor markers lack specificity, and the final diagnosis must be combined with a variety of examinations, such as B-ultrasound, CT, needle biopsy, etc.
It is recommended to go to a regular hospital for a follow-up or other examinations.
