How long malignant ovarian tumor can live mainly depends on the stage, staging and treatment of ovarian tumor as well as the patient’s own situation, which should be analyzed specifically. If the tumor is in the early stage of malignant ovarian tumor or the tumor is less malignant, the tumor cells are only confined to the ovary, the development is slow, no metastasis has occurred yet, and no cancer cells are found through pelvic lymph node examination, the patient can undergo surgery adjuvant chemotherapy or radiotherapy and other treatments, and the survival time is more than 5 years. In case of advanced stage of malignant ovarian tumor or tumor with higher malignancy and extensive implantation metastasis in the abdominal cavity (i.e. tumor cells are shed from the primary tumor and then planted and grown in other parts), patients have a lower 5-year survival rate, and the survival time is usually not more than 2 years. Therefore, it is recommended that women should go to the gynecology or oncology departments of hospitals regularly for corresponding examinations even if they are not uncomfortable, so that early detection, early intervention and early treatment can be made.
