Carcinoembryonic antigen of scalp squamous cell carcinoma is normal, in general, the patient’s antigen data is more normal, the problem is not big, it is recommended that the patient pay attention to the review can be. Specific analysis is as follows: Squamous epithelial cell carcinoma antigen called also known as SCC, squamous cell carcinoma antigen is a kind of tumor marker, which exists in the cytoplasm of squamous epithelial cells of uterus, lung, head and neck, etc., and it has certain specificity and sensitivity. The normal value of squamous cell carcinoma antigen is less than 1.5 ng/L. Many patients such as cervical cancer, squamous lung cancer, esophageal cancer, etc. may have high squamous epithelial cell carcinoma antigen, and the patient’s carcinoembryonic antigen of squamous cell carcinoma of the scalp is normal, which is considered to be not a big problem at present, and it is recommended that the patient pays attention to the rechecking, because it only has auxiliary value in diagnosis, without tension, and it is enough to carry out dynamic monitoring. Carcinoembryonic antigen is a reference index for diagnosing cancer, not a diagnostic index. If the patient has undergone cancer surgery and the antigen data is good, the prognosis is good, and it is recommended that the patient should be rechecked regularly in the later stage.
