The smoothness of the cervix proves that the surface of the cervix is well circulated and free of inflammation, which is the result of a gynecological examination and the doctor’s preliminary judgment with the naked eye. In women who have sexual intercourse, especially if they have contact bleeding or blood in the leukorrhea, the doctor’s visual observation of the smooth surface of the cervix cannot confirm whether there is a malignant lesion in the cervix and requires TCT of the cervix and colposcopic biopsy. In some women, the surface of the cervix is smooth even in the early stage of cervical cancer, and it is only through pathological tests that early cervical tumor cells can be detected. When women have congestion, edema or increased leukorrhea discharge on the surface of the cervix, most of them have cervical inflammation and need to be treated with topical anti-inflammatory drugs and keep the hygiene of sexual life to reduce local vulva infection.
