Radical surgery for ovarian cancer refers to the removal of uterus and adnexa, the cleaning of lymph nodes and the removal of the greater omentum. In most radical ovarian cancer surgeries, the patient’s uterus and adnexa on both sides are removed and lymph nodes are cleared. Because ovarian cancer is more frequent and prone to peripheral lymph node metastasis, lymph nodes around the pelvis and lymph nodes beside the abdominal aorta need to be cleared. Because ovarian cancer can easily metastasize to the greater omentum, radical surgery for ovarian cancer also needs to remove the greater omentum. Some ovarian cancer patients may have mucinous tumor, which may metastasize to the appendix, and appendectomy is needed. Radical ovarian cancer surgery is to reduce the remaining ovarian tumor cells in the body as much as possible, but it is very difficult to achieve complete eradication, that is, it is difficult to achieve 100% removal. When ovarian cancer is diagnosed, it is recommended to seek timely medical treatment and actively treat the disease to improve the quality of life as much as possible.
