Thyroid cancer is a fairly common malignancy. Thyroid carcinomas (cancers) are a heterogeneous group of tumours that demonstrates considerable variability in behaviour, appearance and response to therapy. Although benign thyroid nodules are common, thyroid carcinoma is rare representing approximately 1% of all malignancies and 2% of all cancer deaths.


Thyroid carcinoma occurs with an incidence of approximately 36 to 60 cases per million population per year, ie up to 0.006% per year. These tumours are rare in children and increase in frequency with increasing age. A female to male ratio of 2.5:1 is reported. Incidence in Bombay is 0.4/100,000 in males and 1.0 per 100,000 in females. 

Since 1975 in the USA, the incidence of thyroid cancer in women has more than tripled from  6.5 to 21.4 per 100,000 women, mostly from papillary cancer and mostly in younger women.   Annual mortality from thyroid carcinoma in the United States is only 6 per million population and this has remained stable even though the incidence hastripled.  This discrepancy between incidence and mortality has been interpeted to reflect the favorable prognosis for most thyroid carcinomas; alternatively an overdiagnosis of thyroid tumours as cancer rather than benign growths.
