Ovarian cysts can be distinguished from benign cysts by the duration of the disease, the location of the disease and its growth. 1. Duration of the disease: benign ovarian cysts have a longer duration and grow slowly. Malignant ovarian cysts are shorter in duration and grow faster. 2. Site of development: benign ovarian cysts develop in one ovary. Malignant ovarian cysts usually develop in both ovaries and may invade neighboring organs. 3. Growth: benign ovarian cysts have a smooth surface, fair mobility, clear borders, usually no obvious blood flow signals, and low tumor markers. Malignant ovarian cysts are solid or cystic, tumor markers are increased significantly, often with pelvic and abdominal fluid accumulation, accompanied by abdominal distension. If there is any abnormality in the organism, it is recommended to consult a doctor in time, clarify the cause of the disease with the help of a doctor, and carry out targeted treatment or therapy.
