A doctor also may take out lymph nodes or tissue around the cancer. Radiation therapy can be used alone or in addition to surgery. If the doctor removes all the cancer that can be seen at the time of the operation, the patient may be given radiation therapy after surgery to kill any cancer cells that are left. Radiation therapy given after an operation when no cancer cells can be seen is called adjuvant radiation therapy. Hormone therapy uses hormones to stop cancer cells from growing.
Chemotherapy uses drugs to kill cancer cells.
Chemotherapy may be taken by pill, or it may be put into the body by a needle in the vein or muscle. Chemotherapy is called a systemic treatment because the drug enters the bloodstream, travels through the body, and can kill cancer cells outside the thymus. Treatment by stage Treatment of malignant thymoma depends on the stage of the disease, and the patient's age and overall condition. Standard treatment may be considered because of its effectiveness in patients in past studies, or participation in a clinical trial may be considered. Not all patients are cured with standard therapy and some standard treatments may have more side effects than are desired.
