I had thyroid surgery on 8/28 for thyroid nodule. I am 32 year old female. I have family history of thyroid nodule,thyroid disorders and cancer all of them are females including my mother. Can thyroid nodule that was cystic on all of my test change all of the sudden to hard solid nodule? What can it indicate if it is turned to solid all of the sudden? My doctor was surprised that it was very hard solid nodule without calsification during surgery. He removed my right lobe. He did a frozen section and it came back benign but confused that it turned out to be very hard solid so he sent it out to a lab in Penn to be sure. What are my chances that it stays benign? Why would it change to a very hard solid nodule after it was confirm to be cystic? He told my mother that the test results before surgery was all cystic and was stumped? I had 3 nodules this one was 1.7 cm and the other two were small(just mm). This was all discovered in June when I went to get my lymph node checked being that it was swollen but no infection. I had FNA in Aug showed benign with follicular cells and hurthle cells changes. These nodules were not there last year or six months ago according to my doctor so it showed up out of no where.
