2nd biopsy on thyroid tomorrow

Hi 

I am having a 2nd biopsy on 2 lumps I have on either side of my thyroid tomorrow. The last one I had was benign but doc said it can be false negative??

They are both 3cms and if I’m being honest I would prefer them to take them out. When I swallow food it feels like food gets stuck (only slightly though)

Guess I will know more tomorrow.

Is 3cm large for a thyroid nodule and can anyone think of any questions I can ask please?

Thanks

David.
