The difference between ovarian cysts and ovarian tumors is seen in the following points: 1. Ovarian cysts are benign ovarian tumors, while ovarian tumors include benign ovarian tumors as well as malignant tumors. 2. Smaller ovarian cysts without discomfort can be examined by regular ultrasound. If the ovarian cyst is larger, with a diameter of 5cm or with bleeding, torsion or rupture, it needs to be given surgery in time, which is not likely to lead to recurrence after surgery. If the ovarian malignant tumor, growing faster, cannot be completely removed during the surgery, comprehensive radiotherapy and chemotherapy are needed to treat it after the surgery, which will easily lead to recurrence and pose a serious threat to women’s lives. 3. Very few ovarian cysts have a tendency to become malignant, and all malignant tumors of the ovary are malignant, all of which will metastasize and have a negative impact on health.
