Small cervical cysts can be left untreated. Cervical cysts are usually caused by chronic cervicitis or cervical injury stimulation. During the healing process of cervicitis or cervical injury, secretions in the cervical glands are blocked in the cervical ducts and cannot come out, and cervical cysts are formed. When cervical cysts are relatively small and without symptoms, they do not need to be treated. It is better to do a routine gynecological examination once a year and to do cervical cancer prevention tests such as cervical TCT and cervical DNA. If the cyst is accompanied by cervicitis, treatment is needed, such as microwave, freezing, laser, etc. It is also better to have cervical discharge examination to observe whether there is HPV infection, etc. If there is, antiviral treatment is needed.
