They are surgery, radiation therapy, and hormone therapy. They are also testing chemotherapy as a treatment method. In surgery the cancerous sections of tissue are removed. This is the most common method of treatment. Radiation therapy can be used alone or with surgery.
Chemotherapy is a treatment that uses drugs to kill the cancer cells.
It is either given in pill form or taken intravenously. For noninvasive thymoma the treatment is usually surgery but there have been some rare cases of radiation therapy used. For invasive thymoma they can use surgery and then radiation, radiation therapy alone, a clinical trial of chemotherapy, a trial of chemotherapy followed by surgery, and a trial of chemotherapy followed by radiation if the cancer cannot be removed by surgery. There is no known cause for thymoma. It occurs in mid to late life and is rare in children and teens.
