Currently, teratomas are relatively common in clinical practice, and there is a high probability that teratomas are benign, with most teratomas being benign. The definitive diagnosis requires surgical removal of the teratoma, followed by routine pathological examination post-surgery. The nature of the teratoma, whether benign or malignant, is determined based on the pathological examination, and the results of the pathology dictate the next steps in the treatment plan. If the teratoma is malignant, further follow-up treatment is necessary.
