If a teratoma is confirmed, it is recommended that the patient undergo surgery immediately to confirm the diagnosis. The surgery for teratoma can be divided into minimally invasive and open surgery. Due to the development of current medical techniques, most teratomas can be operated on using laparoscopy, which is characterized by faster recovery and less trauma. However, in certain special cases, such as when the teratoma is large or the patient is overweight and has a number of other chronic diseases, open surgery can be chosen.
