At what size of adnexal teratoma is surgery recommended?

If the benign adnexal teratoma is larger than 5 cm, surgical resection is generally recommended; if it is a malignant adnexal teratoma, surgery is recommended, as follows:

1. Benign adnexal teratoma: If it is a relatively small benign adnexal teratoma with a diameter of less than 5 cm and no clinical symptoms, regular pelvic imaging CT examinations can be performed and surgical resection is generally not required. If the diameter exceeds 5 cm and causes abdominal pain, surgical resection is recommended, and the affected side can be performed with adnexectomy or tumor resection.

2. Malignant adnexal teratoma: Pelvic imaging CT, MRI, and tumor marker CA125 can be combined. If a malignant adnexal teratoma is suspected, surgical resection is recommended and then sent for pathological examination. If it is malignant, further chemotherapy is required to inhibit the proliferation of cancer cells and improve the patient's quality of life and survival period.

Patients with adnexal teratoma are advised to seek medical attention in a timely manner and receive standardized treatment under the guidance of a physician to avoid delaying the disease.
