Figure 17-3: Mild iodine deficiency associated or not with smoking, presence of natural goitrogenic, drugs, familial goiter, genetic markers and gender (women) will decrease the inhibition of serum T4 on the pituitary thyrotrophs. Increased TSH production will cause Diffuse goiter followed by nodule formation. Finally, after decades of life, a large multinodular goiter is present with cystic areas, hemorrhage, fibrosis and calcium deposits.

  • Diagram showing stage T1a thyroid cancer

·         T1a – the tumour is entirely inside the thyroid and is less than 1cm across in any direction


  • Diagram showing stage T1b thyroid cancer


·         T1b – the tumour is entirely inside the thyroid and is more than 1 cm but no more than 2cm across in any direction

  • Diagram showing stage T2 thyroid cancer

·         T2 – the tumour is entirely inside the thyroid and is more than 2cm but no more than 4cm across in any direct

  • Diagram showing stage T3 thyroid cancer

·         T3 – the tumour is more than 4cm across or it has begun to grow into tissues close to the thyroid

  • Diagram showing stage T4a thyroid cancer

·         T4a – the cancer has grown outside the covering of the thyroid gland into nearby soft tissue, such as the voice box (larynx), windpipe (trachea), food pipe (oesophagus) or the voice box nerve (recurrent laryngeal nerve). T4a thyroid cancer is called moderately advanced thyroid cancer.


  • Diagram showing stage T4b thyroid cancer



·         T4b – the cancer has grown outside the thyroid gland into the area surrounding the bones of the spine, or one of the main blood vessels in the neck area. T4b thyroid cancer is called very advanced thyroid cancer.
