Carcinoembryonic antigen with a value of 7.29ng/ml belongs to elevated carcinoembryonic antigen, which may be caused by cancer, but also by smoking, women’s pregnancy, cirrhosis of the liver, cardiovascular disease, and so on. Carcinoembryonic antigen belongs to broad-spectrum tumor markers, and clinics have shown that elevated carcinoembryonic antigen is commonly found in colorectal cancer, gastric cancer, pancreatic cancer, breast cancer, lung cancer, liver cancer and so on. However, smoking, lung disease, hepatitis, liver cirrhosis, diabetes, cardiovascular disease, colitis, pancreatitis, pregnancy, and other diseases or factors can also lead to elevated carcinoembryonic antigen. It can be seen that elevated carcinoembryonic antigen is not a specific marker for malignant tumors, but only plays an auxiliary role in diagnosis. To know whether the carcinoembryonic antigen value of 7.29ng/ml is caused by cancer or not, it is necessary to undergo further examination under the guidance of doctor, such as ultrasound, CT or MRI, in order to make a clear diagnosis. If the test report shows carcinoembryonic antigen value of 7.29ng/ml, the patient should consult the doctor in time, and if necessary, undergo further examination to find out the cause and take corresponding treatment measures.
