Benign teratomas, although not aggressive or metastatic, do not require adjuvant chemotherapy or radiation therapy after curative surgery to fight the tumor. However, many benign teratomas recur after surgery and require further surgical treatment. The cause of benign teratoma recurrence is considered to be due to the persistent presence of oncogenic factors. Therefore, benign tumors can also recur, since the exact cause and pathogenesis of benign teratomas are still unclear clinically. Thus, prevention from an etiological perspective is not possible, and the only option is timely surgical removal upon tumor detection to prevent the benign teratoma from becoming malignant. For patients with benign teratomas, regular follow-up is necessary after curative surgery to monitor any changes in the condition. If signs of recurrence are detected, prompt intervention is necessary to prevent malignancy.
