The full name of scc is called squamous cell carcinoma antigen, which is a glycoprotein-based tumor marker. The causes of high squamous cell carcinoma antigen are generally divided into tumor factors and non-tumor factors. 1. Tumor factors: high squamous cell carcinoma antigen may appear in squamous cell carcinoma, such as esophageal squamous carcinoma, cervical squamous carcinoma, lung squamous carcinoma, but squamous cell carcinoma antigen cannot be identified as squamous cell carcinoma, and it needs to be judged according to the relevant examination results. 2. Non-tumor factors: benign lesions and inflammatory lesions in the body may also lead to high squamous cell carcinoma antigen, such as esophagitis or cervical inflammation. Therefore, cancer cannot be diagnosed solely on the basis of high squamous cell carcinoma antigen. Patients with high squamous cell carcinoma antigen need to combine with their clinical symptoms and test results to confirm the diagnosis.
