Elevated carcinoembryonic antigen is not necessarily a manifestation of metastasis and recurrence, and needs to be combined with clinical symptoms and other auxiliary examinations for comprehensive judgment.
1. Carcinoembryonic antigen is a glycoprotein, which exists in endodermal cells. Carcinoembryonic antigen can also be seen increased in gastric ulcer and atrophic gastritis. Sometimes distant metastasis and recurrence may occur when carcinoembryonic antigen is at normal value.
2. Elevated carcinoembryonic antigen can be combined with CT, ultrasound, gastroenteroscopy and tissue biopsy to determine the presence of metastasis and recurrence.
If the test result of carcinoembryonic antigen is abnormal, it is recommended to consult a doctor in time to clarify the cause of the disease under the guidance of a professional doctor and carry out targeted treatment or therapy.
