Ovarian junctional tumors are not considered carcinomas. Ovarian junctional tumors are tumors between benign and malignant. The microscopic characteristics of junctional tumors are active epithelial cell proliferation without obvious mesenchymal infiltration, and the clinical characteristics are slow growth and late recurrence. In recent years, the term “junctional tumors” has been renamed “atypical hyperplastic tumors” because there is no evidence that some junctional tumors (e.g., mucinous tumors) have malignant behavior. Therefore, ovarian junctional tumors can not be said to be cancer, but after the discovery of ovarian junctional tumors, it is also necessary to carry out timely treatment to avoid the further development of the disease, and to reduce the more serious harm caused by this disease to oneself.
