First of all, it needs to be clarified what kind of cyst it is. Ovarian cysts are one of the common conditions in obstetrics and gynecology. Many women are found to have ovarian cysts during medical checkups. Therefore, the treatment of ovarian cysts is an issue of concern for the majority of women. The current clinical treatment of ovarian cysts requires a comprehensive judgment based on the type, size and nature of ovarian cysts. If the ovarian cyst is less than 4 cm in diameter. If the ovarian cyst is less than 4 cm in diameter and the relevant laboratory tests do not indicate a malignant tendency, then it is recommended that the patient can be observed regularly. The gynecological ultrasound can be reviewed every six months to observe the changes of ovarian cysts. If the ovarian cyst is less than 4 cm in diameter but is cystic and does not disappear, then the patient is advised to undergo surgery as soon as possible after completing the relevant investigations. If the ovarian cyst is larger than 4 cm in diameter and persists, surgical treatment is recommended. It is important to note here that ovarian cysts are small and physiological follicular development needs to be excluded. Such physiological ovarian cysts can generally disappear on their own after menstruation and do not require special treatment. Therefore, to review for ovarian cysts, it is generally more accurate to choose to do ultrasound within 3 days of menstruation. As mentioned above, the treatment of ovarian cysts needs to be selected on an individual basis and different treatment methods are needed for different cases.
