I am a 59 year old woman and I had a partial thyroidectomy about 20 years ago due to nodules and cysts. The biopsy was clean so no cancer. I have recently had another ultrasound because of thyroid enlargement. I have nodules with calcification on the other half now. I had a needle biopsy done and the report said there were not enough cells to determine anything. My endo said to wait 6 months and do another ultrasound and possibly another needle biopsy later. I know the calcification means it is a greater risk of it being cancer and I am wondering if it is wise to wait 6 months instead of doing a surgical biopsy. I want a second opinion, but don't know if I should go to another endo or throat specialist.
