I was diagnosed with paraganglioma, what is this?

Benign lesion: Paragangliogliomas are generally NOT considered cancer. They are benign tumors that can occur anywhere along the pathway of the sympathetic nerves. If they are not causing symptoms, they can just be followed with annual clinical exams and imaging. If they are causing symptoms, there are different treatment options available (medications for endocrine secreting tumor, radiosurgery, or surgery)
