Benign reactive changes on TCT means that no malignant tumor cells, no atypical squamous cells and no atypical glandular cells are seen in the cervix, which can initially exclude the possibility of cervical cancer and precancerous lesions, and benign reactive changes on TCT may be caused by cervicitis. Cervicitis may be caused by cervicitis. TCT may indicate benign reactive changes, mainly due to infection caused by pathogens after childbirth, miscarriage or surgical injury to the cervix. The local manifestations of cervicitis are mostly cervical hypertrophy, cervical ductitis, cervical glandular cysts and cervical squamous epithelial metaplasia. Most patients have no obvious clinical symptoms, and some patients may show increased leucorrhea, which is milky or slightly yellow, mucousy-purulent, sometimes bloody or interspersed with blood. Patients with abnormalities can undergo vaginal B-mode ultrasonography, colposcopy to locate biopsies, and after a clear diagnosis, they can follow medical advice for treatment, such as using medications and physical therapy such as freezing and laser to relieve inflammation. In daily life, women also need to maintain personal hygiene, wash their vulva with water every day, and take safety measures during sex to avoid infection.
