What is thymoma?

Thymoma is a tumor of the thymus gland which is located in the chest behind the breast bone. In children, the thymus gland produces immune cells, but in adulthood the thymus gland no longer serves an important function. Thymomas can be slow growing or can be more aggressive and spread in the blood stream. Thymic carcinomas are the most aggressive tumors of the thymus gland.

Thymomas may cause symptoms or be found by chance on chest X-rays or CT scans done for other reasons. Thymomas are associated with myasthenia gravis, an autoimmune disease causing muscle weakness. Very large thymomas may also cause symptoms such as cough and shortness of breath. If the thymoma appears small, your surgeon may recommend surgical removal without a biopsy. But if the tumor is large or if the diagnosis of thymoma is not certain, your surgeon may recommend that you undergo a CT-guided core needle biopsy, which is done in radiology.

Every patient is different, with different needs. At City of Hope, we treat you as a valued individual. Our entire thymoma team works together to bring you advanced surgery, chemotherapy, radiation and supportive care options that will deliver the best clinical and functional outcomes for you. You can also enroll in clinical trials for promising treatments that are not offered elsewhere.

For resectable thymomas, surgical removal of tumor is the mainstay of treatment. Patients with advanced thymoma typically receive chemotherapy prior to surgery, and may receive radiation therapy after surgery.

Your care continues long after treatment is completed, and we are committed to helping you and your loved ones manage your recovery.
