For patients with teratoma, once the teratoma is detected, it is necessary to monitor it regularly. If the tumor is larger than three centimeters, it is best to undergo surgery as soon as possible. If surgery cannot be performed promptly due to particular reasons, then it is essential to have an ultrasound re-examination every three months. Additionally, patients should avoid vigorous exercise, external impacts, and significant changes in body position in daily life. Because teratomas are mixed masses with uneven textures, they are very prone to torsion. Therefore, significant changes in body position or vigorous exercises can easily cause the torsion of the pedicle, which may lead to the need for emergency surgery.
