Hello, I have had 2 biopsies on my thyroid nodules. The small one on the right was problematic , and I am waiting for my endochinologist for further information, about Alta Bates Hospital s Pathologist s approval for an indepent pathologist from S. San Francisco to meet at Alta Bates, take an another biopsy and take it back for something called an Affirma or Afirma test. I don t even understand what they are looking for. I am not fat. The nodule on the left was enormous, and came back normal . Can you explain to me what this thyroid (very small on the right) is all about. I am 5 6 and weigh around 115 lbs.
