Factors affecting the elevation of SCC include tumor disease factors such as lung cancer, cervical cancer, and head and neck cancer, as well as non-tumor disease factors such as cervicitis, esophagitis, and cholangitis. The full name of SCC is squamous cell carcinoma antigen, which is a tumor indicator that can be detected in serum. Generally, under normal circumstances, the value of SCC in serum is maintained at a low level, and when suffering from some tumors or non-tumor diseases, this indicator may be elevated, which is generally used as an auxiliary diagnostic indicator for some malignant tumors at present. Lung squamous carcinoma, cervical squamous carcinoma, or head and neck squamous carcinoma and other malignant tumors will often cause a significant increase in serum SCC. There are also some non-tumor inflammatory diseases that may cause mild elevation of SCC, such as cervicitis and cholangitis.
