As people become more health conscious and have regular annual checkups, cysts can be found during unintentional examinations. Common gynecological cysts have different names depending on where they occur; if they occur in the ovaries, they are called ovarian cysts; if they occur in the cervix, they are called cervical cysts. There are two types of ovarian cysts; one is physiological, which is usually not large and does not exceed 5 cm in diameter and does not require treatment, and can be observed on a follow-up basis. The other is pathological, that is, the cysts are really bigger than 5 cm in diameter and are always present on ultrasound within 3-7 days of menstruation. The formation of cervical cysts is mainly due to the non-permeability of the glandular ducts of the cervix, resulting in the accumulation of secretions at the end of the inside. As for the treatment of cervical cysts, if the cervical cysts are small and there is no increase in leucorrhea or abnormal leucorrhea, there is no need for treatment; when the cervical cysts are large and abnormal, it is possible to perform local surgery. To sum up, regardless of the site where the cyst occurs, the treatment of the cyst is decided according to the different sizes of the cyst and the presence or absence of uncomfortable manifestations. If the cysts grow larger in a short period of time, especially ovarian cysts must go for active treatment.
