Treatment involves removing the tumor with surgery. It is important to stabilize blood pressure and pulse with medication before surgery. You may need to stay in the hospital.

After surgery, it is necessary to continually monitor all vital signs in an intensive care unit. When the tumor cannot be surgically removed, medication is needed to manage it. Radiation therapy and chemotherapy have not been effective in curing this kind of tumor.

About 95% of patients who have noncancerous tumors that are removed with surgery are still alive after 5 years. The tumors come back in less than 10% of these patients. Release of the hormones norepinephrine and epinephrine returns to normal after surgery.

Less than 50% of patients who have cancerous tumors that spread to the bones, liver, or lung are alive after 5 years.

High blood pressure may not be cured in 25% of patients after surgery. However, standard treatments can usually control high blood pressure. In about 10% of people, the tumor may return.
