Low-grade ovarian cancer refers to ovarian cancer with relatively high degree of differentiation and low degree of malignancy, and the specific treatment plan needs to be judged comprehensively with the condition of the disease, which mainly includes surgical treatment, radiotherapy, targeted therapy and daily care. 1. Surgery: commonly used in early stage ovarian cancer, which can completely remove the lesions and has a relatively good prognosis. Advanced patients can also choose palliative surgery, which can delay tumor progression and reduce symptoms. 2. Radiotherapy: for preventing recurrence and metastasis after surgery or advanced stage patients, radiotherapy can be chosen for control. Radiotherapy is mainly for the surgical area or for the area with large lesions and symptoms; chemotherapy is mainly applied to chemotherapeutic drugs, such as cisplatin and so on. 3. Targeted therapy: some ovarian cancer patients can choose to apply targeted drugs, which can achieve the therapeutic purpose by inhibiting the formation of tumor neovascularization, and commonly used drugs include Olaparib. 4. Daily care: during the treatment period, patients should pay attention to adjusting diet, matching nutrition, enhancing physical quality, and trying to regulate the physical condition as much as possible. When low-grade ovarian cancer is found, one should seek medical treatment as early as possible and carry out standardized treatment under the guidance of clinicians to prevent the disease from progressing.
