SCC value of 2.2 belongs to the mild elevation of tumor indicators, if the indicator is abnormal caused by malignant tumors, it is usually more serious, if it is elevated caused by some non-tumor diseases, it is usually less serious. SCC is squamous epithelial cell carcinoma antigen, is a kind of hematological tumor marker used to assist in diagnosis, assessment of treatment effects and monitoring of disease changes, generally its normal value range is less than 1.5, so the indicator 2.2 is a mildly elevated, the reasons for the elevation of this indicator are mainly considered to be malignant tumors, or non-malignant diseases. Malignant tumors that cause elevated SCC include lung cancer, cervical cancer, etc. These diseases are more serious as they can present a variety of clinical symptoms, affecting the quality of patient’s survival and may lead to a shortened survival period. Elevated SCC caused by cervicitis, esophagitis and other non-tumor diseases is generally not serious as the index will return to normal after anti-inflammatory treatment.
