Re: Thyroid Cancer?
I think you lost the rest of your post?
Cysts (that is fluid filled) on the thyroid are rarely cancerous. If you have a solid or cystic thyroid nodule around 1cm, you will need a needle biopsy. Nodules are common, 95% are benign, and they just happen.
I doubt you have to worry, but thyroid cancer is rare, and it's actually curable....so don't worry---and they can't tell anything at all in terms of malignancy from an ultrasound.
