Most often times the answer to that is in your paperwork - if you signed a consent form saying they are allowed to - they can. Though if you are just being scoped and having a small amount of tissue removed it's unlikely since it's a more invasive procedure. can they as in physically? Yes - they could technically go in and remove it. They can pretty much do anything. But it often depends on consent, or time, preparedness ( were the thinking of doing it based on the look of you thyroid - etc.) also depending on the doctor one procedure requires you to be put under where as the other may not (we used to do broncos copies with just freezing! But his all depends on the context if your question... Are you hoping they will or afraid they will. Best to ask your dr. Good luck.
