Could you tell me what is the pathogenesis of thyroid cancer?

Often unknown.: Thyroid cancer is the most common cancer of the endocrine glands. It is most common in individuals with history of exposure of the thyroid gland to radiation, in individuals with family history of thyroid cancer and in those older than 40 years of age. The exact cause of cancer in an individual patient is most often unknown. I am providing a link in the comment section with good information.
