An elevation of squamous epithelial cell carcinoma antigen during the test usually indicates that the patient may have squamous cell carcinoma or cancer recurrence, because squamous epithelial cell carcinoma antigen itself is a tumor marker, and if it is significantly elevated during the blood test, it indicates that the patient may have cancer or cancer recurrence and may have reached the middle or late stage. The diagnosis cannot be confirmed by elevated squamous epithelial cell carcinoma antigen alone, and further pathological examination is required to confirm the diagnosis. Although the elevation of squamous epithelial cell carcinoma antigen can reflect the possible presence of tumor, it is not only the tumor that causes the elevation of squamous epithelial cell carcinoma antigen, but cytological examination and pathological analysis are needed to determine whether there is malignant tumor formation or recurrence of cancer. For the more common squamous epithelial cell carcinoma of the uterine cervix, a cervical biopsy followed by a cervical smear is required to confirm the diagnosis, and depending on the extent of tumor spread, surgery or chemotherapy is required to control it.
