What kind of thyroid nodules should be suspected of cancer

Thyroid cancer should be ruled out if thyroid nodules are isolated, especially if they are hard and uneven, accompanied by enlarged lymph nodes in the neck, recurrent laryngeal nerve paralysis, or a history of radiation in the neck. In addition, thyroid cancer should be suspected if one of the multiple thyroid nodules is prominent and hard. In addition, thyroid cancer should be considered if the thyroid itself shows asymmetrical enlargement or induration, rapid growth, or fixed location. Thyroid nodules are clinically common and an experienced sonologist can make an initial grade assessment of thyroid cancer risk.
