Carcinoembryonic antigen 1.3 generally refers to carcinoembryonic antigen 1.3ng/ml.Carcinoembryonic antigen 1.3ng/ml belongs to the normal range of lung cancer patients, which is generally a good phenomenon, indicating that the condition of lung cancer is more stable.
Under normal condition, carcinoembryonic antigen should be <5.0ng/ml, at present, the carcinoembryonic antigen of lung cancer patient is 1.3ng/ml, which is within the normal range. Generally, the serum carcinoembryonic antigen concentration decreases when the cancer improves and increases when the disease worsens. Therefore, a normal carcinoembryonic antigen indicates that the tumor in the patient’s body is under good control, developing slowly or with a higher degree of differentiation, which is a better phenomenon.
However, carcinoembryonic antigen is only used as an indicator to assist in judging the prognosis, and cannot diagnose whether the disease is serious or not. Therefore, lung cancer patients need to undergo other examinations, such as CT examination of the lungs, etc., in order to combine the results of several tests to determine whether the lung cancer is serious or not.
It is recommended that lung cancer patients should follow the doctor’s instructions to have regular treatment as soon as possible and have regular checkups during the treatment.
