A naevus cyst is not chronic cervicitis. Nasal cysts are caused by the squamous epithelium in the transformation zone of the cervix in the process of replacing the columnar epithelium, so that the new squamous epithelium covers the glandular opening of the cervix or extends into the gland ducts to block the glandular opening. While chronic cervicitis is mainly caused by pathogenic infections, common pathogenic infections include Chlamydia trachomatis, Neisseria gonorrhoeae, etc., so Nana cysts are not chronic cervicitis. Patients with Nana cysts should pay attention to vaginal hygiene and cleanliness to avoid infection. Patients with chronic cervicitis should change their underwear regularly and should wear cotton comfortable underwear. The treatment of Nana cysts and chronic cervicitis requires an experienced doctor to diagnose and treat the disease. It is recommended that patients go to a regular maternity hospital for examination, to clarify the cause of the disease, and then carry out targeted treatment, patients should actively cooperate with the doctor for treatment.
