Ovarian teratoma grows more slowly if it is benign and more rapidly if it is malignant. If a teratoma is found, surgery is recommended to give treatment as soon as possible. Most of the teratomas are benign, but there are also malignant ones, so after surgery, the excised tissues must be sent for pathological examination, and the next step of treatment should be decided based on the results of pathological diagnosis. If the tumor is benign, it should be reviewed regularly. If it is malignant, the next step is chemotherapy to give the appropriate treatment. It is recommended that women should have a gynecological examination once a year to find out whether there are pelvic tumors, cervical cancer or inflammation, and then deal with them according to the results.
