Ovarian cysts, as one of the common gynecological diseases, pose a certain risk to women’s health. Its clinical symptoms can vary according to its size, nature, location, development and the presence of complications. Usually, ovarian cysts have no clinical symptoms in the early stage of development, and if they are physiological, they will also disappear on their own with the menstrual cycle. If the cyst reaches a certain size, the discomfort in the lower abdomen will appear. On physical examination, there is a feeling of swelling and falling in the lower abdomen or skeletal fossa, and a mass in the abdominal cavity can be palpated by pressing on the lower abdomen, which is painless when touched and has good mobility. If the ovarian cyst is torsional, the symptoms of acute abdomen such as severe abdominal pain and distension, nausea, etc. may occur. If the cyst is malignant or if there is an inflammatory reaction, peritoneal irritation signs and ascites will appear. In the case of advanced malignant tumors, there are more symptoms, such as weight loss, painful face and severe systemic failure. Since ovarian cysts have no symptoms in early stage, but can be detected by abdominal ultrasound and gynecological examination, it is recommended that women have regular gynecological examination every year for early detection and early diagnosis and treatment.
