There are various categories of thyroid cancers that are found in tumours based on cells. These are papillary thyroid cancer, follicular thyroid cancer, anaplastic thyroid cancer, and medullary thyroid cancer, as shown in Figure 3.2.

There are various categories of thyroid cancers.

 • Papillary Thyroid Cancer: Papillary thyroid cancer occurs mostly in children and women and grows very slowly. The common type of thyroid cancer is papillary thyroid cancer. This type of cancer occurs at any stage but is mostly affected between the ages of 30 and 50 [6].

 • Follicular Thyroid Cancer: This is the second most common type of cancer caused by the thyroid and is less common than papillary thyroid cancer. This type of cancer mostly affects people above the age of 50 years. It is also a type of behavioral thyroid cancer but the thyroid has a slightly higher risk of spreading than papillary cancer [6].

Figure 3.2 Categories of thyroid cancer.

 • Anaplastic Thyroid Cancer: Anaplastic thyroid cancer has rapidly developing, poorly differentiated thyroid cancer that can begin with differentiated thyroid cancer or a benign thyroid tumor. It is often seen in patients who have prolonged thyroid inflammation. It spreads rapidly to both local and distant organs [6].

 • Medullary Thyroid Cancer: Medullar thyroid cancer spreads more than other types of cancer. It is a special type of thyroid cancer that is hereditary in many patients. This type of cancer occurs in young children and can be treated well with adequate surgery [6].
