Ovarian tumors are tumors that occur on the ovaries. Ovarian tumors are common tumors in the female genitalia and their severity is related to the benignity and malignancy of the tumor. Usually, malignant tumors are serious and have a high mortality rate. Ovarian tumors vary in form and nature. There are cystic, solid, benign and malignant tumors, with cystic being the most common. Benign ovarian tumors have no obvious symptoms and signs in the early stage, and most of them are found during gynecological examination with ultrasound, so they can be left untreated for the time being, and the dynamic changes can be observed by regular ultrasound examination. In medium-sized ovarian tumors, they may cause intra-abdominal masses, which are mobile and can move from pelvic cavity to abdominal cavity; they may also cause abdominal pain, abdominal distension, and even irregular vaginal bleeding. In this case, it is recommended to seek medical attention in time and give symptomatic treatment, and the prognosis is mostly good. Malignant ovarian tumors grow rapidly, the masses are irregular and immobile, and may be accompanied by ascites, and systemic symptoms such as weakness, fever and loss of appetite may appear within a short period of time. When malignant ovarian tumors appear, immediate medical attention should be sought and, if necessary, surgical resection and radiotherapy treatment should be performed. Although great progress has been made in recent years in both basic research and clinical management of ovarian malignancies, unfortunately, the 5-year survival rate has not been significantly improved. Therefore, when ovarian tumors are detected, it is important to actively review them to determine their nature and actively give symptomatic treatment.
