Paraganglioma (adrenaline-producing tumor outside the adrenal gland)
Do I need follow-up after surgery?
Yes. Paragangliomas can recur (i.e. come back) at the original site, in the opposite adrenal gland, in other extra-adrenal sites, and at sites distant from the original tumor (metastatic disease to bone, lung, liver). This can take place even more than 20 years after the original operation. Therefore, patients should undergo life-long yearly blood tests (plasma metanephrines).
