Hello friend, question is very difficult to answer. Reason being, every individual is different. If you/hubby do not feel confident, comfortable, assured with surgeon, alway's seek another opinion.
First surgeon I spoke with, I didn't feel comfortable with at all, reason I cancelled surgery. 2nd surgeon discussed options, answered all my questions for 1.5 hrs, I felt complete comfort with him to perform thyroidectomy, he was very friendly, patient, understanding,.
When you/hubby visit surgeon for follow up, ask why surgeon feels monitoring is best option opposed to surgery, Etc....
Wishing you/hubby well :)
