The cure rate of ovarian cancer in early stage is very high clinically. If early detection of ovarian cancer does not show metastasis and the cancer is only limited to the ovary, early surgery is given for treatment and the cure rate is higher through chemotherapy after surgery. It is recommended that women should have a gynecological examination once a year even if they are not in discomfort. The purpose of gynecological examination is to exclude the inflammation of the reproductive tract and the possibility of gynecological tumors. For malignant tumors in gynecology to achieve early detection, early treatment and early intervention, the cure rate will be improved clinically, the quality of life of patients will be improved, and the life of patients will be prolonged. For women, annual gynecological examination is very important. If abnormal pelvic masses are found during gynecological examination, combined with clinical history, three gynecological tumor laboratory tests can be done when necessary to understand whether carcinoembryonic antigen and carcinoma antigen are abnormal. In clinical practice, it is possible to make a preliminary diagnosis of whether the abnormal mass is benign or malignant and decide the next treatment plan.
