Hi I wonder if anyone has had a fine needle aspiration after an ultrasound scan found a darkened nodule on the thyroid. I'm not even sure what a darkened nodule is? I had the fine needle aspiration yesterday and just anxiously waiting on results a darkened nodule wasn't even in my radar so now a bit confused over it all. Lots of questions running about in my head like If it's not cancer then what else could it be if it is cancer how soon do I get results!! Can anyone explain a darkened nodule to me please? :)
