SCC is squamous cell carcinoma antigen, and further examination is recommended to exclude the presence of malignant tumors. Squamous cell carcinoma antigen is a common auxiliary diagnostic index and prognostic monitoring index for clinical tumors. Elevated squamous cell carcinoma antigen is commonly found in squamous carcinoma, including cervical squamous carcinoma, nasal carcinoma, skin carcinoma, lung carcinoma and so on. If squamous cell carcinoma antigen is significantly elevated, it suggests the possibility of malignant tumors, and one should go to the hospital in time for relevant examinations, such as head and neck CT or MRI, chest CT, gynecological ultrasonography and so on, in order to detect the presence of malignant tumors in time. After ruling out the presence of tumor, regular review is sufficient. If squamous cell carcinoma antigen is significantly elevated, it is recommended to consult a doctor in time, clarify the cause of the disease under the guidance of a physician, and actively take therapeutic measures.
