Thymoma treatment typically involves surgical removal of the tumor, which is the most common and effective approach, especially if detected early. If surgery alone is insufficient or the tumor is invasive, additional treatments like radiation therapy may be used to target remaining cancer cells. For advanced or recurrent thymoma, chemotherapy or targeted therapy may be considered. In some cases, immunotherapy is used to enhance the body's immune response against the tumor. Treatment is tailored based on the tumor's stage, location, and whether it has spread.
