Most patients feel much better and their blood pressure improves greatly after treatment. A few patients still experience high blood pressure after surgery. Medicine may still be used for blood pressure control in those cases.
Long-term follow-up care is important for everyone after treatment. In very rare cases, pheochromocytomas is cancerous and may come back. This is possible even 15 years, or more, after surgery. This rare cancer can’t be found under the microscopic, so long-term follow-up is required.
Without the right treatment, the severe high blood pressure tied to pheochromocytoma can lead to heart attack or stroke. After treatment, the outlook is good for most patients.
