There has to be a marker in bloodwork to alert thyroid cancer may be present because most ppl have drs who nvr feel their necks so what is a signofit ?

No marker: Most thyroid cancers that are not advanced with lymph node disease present with a solitary adenoma. That is a single, usually small lump about 1-2 cm. that if left to grow will eventually convert. Because the lesion is firm it is usually noted by the patient before the MD. All solitary lesions that are cold on scan should be removed by thyroid lobectomy.
