Which is the most common malignant Tumour of the thyroid?

Types of thyroid cancer

  • papillary carcinoma – the most common type, accounting for about 8 in 10 cases; it usually affects people under 40, particularly women.
  • follicular carcinoma – accounts for up to 1 in 10 cases and tends to affect middle-aged adults, particularly women.

What is the second most common thyroid malignancy?

Follicular thyroid cancer (FTC).

This is the second most common type of thyroid cancer. It is usually found in countries where people do not get enough iodine from food. FTC can spread to the lungs.

Which is the least common thyroid malignancy?

The least common type of thyroid cancer, anaplastic thyroid cancer, has a very poor prognosis. The best results occur when localized anaplastic thyroid cancer is diagnosed early and completely removed via a thyroidectomy, as it’s very aggressive.
