Had a FNA biopsy on my thyroid a week ago and my dr will not return my call??

Be patient. Although you are nervous, be patient. There are a lot of possibilities. The biopsy could be positive for cancer, negative or indeterminant. For this reason, you may need to seek the guidance of an Endocrinologist who has experience with thyroid cancer, if you have not already done so.
Appointment time? If you cannot wait for your next dr's appointment, you do have the right to ask the hospital/clinic for a copy of your biopsy Pathology report.
