Ovarian cystadenoma is a benign tumor. There are more than ten kinds of ovarian tumors, including cystadenoma, teratoma, endometriosis cyst, etc. Cystadenoma is one of them. Any ovarian tumor is divided into benign, junctional and malignant. As long as the tumor is cystic adenoma as indicated by the pathology report after surgery, and there is no mention of junctional and cancerous changes, it is a benign tumor, so don’t worry. The reason for this is that there are very few recurrences of ovarian cystadenoma after surgery because it is benign, but endometriosis cysts and chocolate cysts of the ovary are prone to recurrence, which generally do not recur, as long as the pathology report determines that it is a cystadenoma is benign.
