The primary treatment for immature teratomas is surgical removal of the tumor. The extent of surgery depends on the tumor's size, location, and whether it has spread. In cases where the tumor is confined, fertility-preserving surgery may be an option. In higher-grade tumors or those with metastasis, chemotherapy may be recommended post-surgery. The most common chemotherapy regimen includes drugs such as cisplatin, etoposide, and bleomycin.
