Thank you everyone. As I researched more and spoke to different people this weekend I had decided that a biopsy here locally was just not a wise decision. The doctor I saw admitted to not knowing much about paraganglioma, thus Tue plan to refer me to Mayo Clinic. I think he requested the biopsy as that is probably a normal course of action for other types of tumors he treats.I will certainly be contacting his office on Monday with the information you all have shared and request he proceed with the referral.
