A discussion of treatment options will be based on the results of tests. If surgery to remove the tumor is recommended, the procedure can be done at NIH under this study protocol. If a malignant tumor is found that cannot be treated surgically, chemotherapy or radiation therapy may be recommended. These options are not offered under this protocol, but may be available under a different NIH study (for example, at the National Cancer Institute). Referrals will be made at the patient s request.
