Hi :)

I had a left hemi thyroidectomy on the 5th of Dec 2022 due to an obstructive goiter. I only ever had a CT scan then they discovered my trachea was deviated and skipped the biopsy's etc. Ive had this goiter since I was 3 (now 25) but in the last year it's tripled in size. However my surgeon has never once suspected cancer she thinks it's just a large nodule. 

I got my results back last week and the letter states "they found no concerning finding" but they're sending it away for a second opinion. Has this happened to anyone else? 
I'm confused as to why they're getting a second opinion if there's nothing concerning? 
 

TIA
