Most ovarian cysts are physiological, so few people experience symptoms. Common ovarian cysts include corpus luteum cysts and other ovarian cysts, which generally disappear naturally after two to three months. Therefore, if the ovarian cyst is not large, within five centimeters, and there are no symptoms, it is possible to temporarily observe it and perform an ultrasound after two to three months. If the cyst has not decreased in size or continues to grow, it may be an ovarian tumor, which would require surgical treatment. This is because if an ovarian tumor is left for a long time, it may become malignant or may lead to ovarian torsion.
