Defining Cancer:
Cancer is a common term of tumors affecting nearly every part of the body, there are two types of cancer: benign tumors and malignant tumors (or what called cancerous tumors), and differentiation between them can be done through tissue examination (biopsy).

Thyroid Gland:
The thyroid is a butterfly-shaped gland at the front of the neck that regulates blood pressure, heart rate, body temperature, weight and other vital functions. 

Defining Thyroid Gland Cancer:
Thyroid cancer is a rare type of cancer, and it is more common in the 30s and after the age of 60, and women are 2-3 times more likely to develop thyroid cancer than men.

Types of Thyroid Cancer:
  • Papillary thyroid cancer (the most common form of thyroid cancer).
  • Medullary thyroid cancer.
  • Anaplastic thyroid cancer.
  • Follicular thyroid cancer.
  • Hurthle cells tumor (very rare).
Thyroid cancer occurs when cells in your thyroid undergo genetic changes (mutations). The mutations allow the cells to grow and multiply rapidly. It's not clear what causes thyroid cancer.
