Positive cervical mucus exfoliative cells 16.5 refers to the presence of abnormal cervical mucus cells, which is commonly found in chronic cervicitis, cervical intraepithelial neoplasia and cervical cancer. 1. Chronic cervicitis: chronic cervicitis is usually caused by bacterial or viral infection, due to the constant stimulation of inflammation leads to the damage of the epithelial cells of the cervical mucosa, which results in the positive cervical mucus exfoliative cells. 2. Cervical intraepithelial neoplasia: it means that the epithelial cells of the uterine cervix are replaced by heterogeneous cells to varying degrees, and HPV infection, early sex or sexual disorders are the high-risk factors. 3. Cervical cancer: It is a malignant tumor originating from the cervix, usually caused by persistent high-risk HPV infection. Smoking, multiple sexual partners, early start of sexual life, multiple pregnancies and multiple births are risk factors. When the test result of cervical mucus shedding cells is positive 16.5, you should go to the hospital in time to consult the corresponding department and standardize the treatment under the guidance of professional doctors to improve the prognosis and prevent complications.
