I have a single 12mm nodule (blends in with surrounding tissue) on my thyroid. I am seeing a specialist soon...should I have any tests done before?

Many. thyroid nodule is either solid or cystic and that could be determined by ultrasound then if solid it classified as hot,cold,or warm based on the up take on thyroid nuclear scan we usually worry about cold single solid nodule in young person potential for cancer is higher than the others cystic lesion 99%are benign unless it is mixed specialist might perform fine needle aspiration good luck.
