If high glycogen antigen is found in physical examination, do not be alarmed, you can choose to review it regularly or have further examination. Although glycogen antigen test is mainly used as an auxiliary diagnostic indicator for malignant tumors in clinical practice, a high level of glycogen antigen does not necessarily mean that one has a malignant tumor, and many benign diseases can also lead to high glycogen antigen. Therefore, if a high level of glycogen antigen is found, patients should be carefully observed and asked if they have any uncomfortable symptoms. If there are no other uncomfortable symptoms, you may not need to do any special treatment first and review regularly. If increasingly high levels of glycogen antigen are found, further examination should be carefully performed to exclude possible malignant tumors. If accompanied by uncomfortable symptoms, such as stomach pain and black stools, further examinations such as gastroscopy and colonoscopy should be done to rule out gastrointestinal diseases, including malignant tumors of the gastrointestinal tract. If there are uncomfortable symptoms such as coughing, coughing sputum, hemoptysis, etc., X-ray chest examination, CT examination, etc. are needed to exclude malignant diseases of lung cancer. In conclusion, if you find high blood sugar antigen, it is better to consult a doctor at the hospital and follow the doctor’s advice for examination and treatment.
