The vast majority of cystic masses in gynecology refer to localized cysts in the ovaries. The main reason for this is whether or not the cyst is physiological or pathological. The pathological cysts are certainly more serious and require surgery if necessary, and although the vast majority of pathological cysts are benign, there is a possibility of malignant changes occurring individually, so the excised tissue must be sent to the pathology for laboratory tests after the surgery, and the pathological diagnosis will eventually prevail before the next specific plan can be formulated. If the cyst is physiological, it is not serious clinically, mainly because the corpus luteum does not shrink in time after ovulation, so it will lead to ultrasound examination and find a cyst, then this cyst will often shrink significantly or disappear after menstruation, so clinical treatment is not necessary.
