Hi, I don’t understand why anyone would want to have thyroid surgery unless it is necessary. There is a procedure called radio frequency ablation to shrink nodules that might be beneficial if your testing does not support a suspicion of malignancy. RFA might be able to shrink the nodule so it goes away.
FYI- A lobectomy does not always result in the other lobe producing enough TSH and you end up having to get regulated on Synthroid… something that is not as easy as people think.
I am surprised that a surgeon spoke with you about removing an organ before identifying a need to remove the organ; but I think surgery should always be the last option.
Good luck!
