Ovarian tumors are common tumors of the female genitalia and are classified as benign or malignant. Malignant tumors have a relatively low 5-year survival rate due to the lack of early diagnostic methods. Ovarian tumors are classified into three grades, differentiation grade I is highly differentiated, differentiation grade II is moderately differentiated, and differentiation grade III is poorly differentiated, and poorly differentiated has a poor prognosis. Primary ovarian malignant tumors are divided into four stages; stage I is when the tumor is confined to the ovary, stage II is when one or both ovarian tumors are accompanied by intra-pelvic spread. Stage III is one or both ovarian tumors with microscopically confirmed extra-pelvic abdominal metastases, regional lymph node metastases, and liver surface metastases. Stage IV is the presence of distant metastases, except abdominal metastases. Ovarian malignant tumors do not have symptoms in the early stage, and the symptoms are mainly abdominal distension, abdominal mass and ascites, and in the late stage, there can be lethargy, severe anemia and other malignant states. Surgery is the first choice for treatment, and the earlier the surgery, the better the therapeutic effect.
