Types and Indicators of Thyroid Cancer

Thyroid cancer is cancer that leads to excessive growth of cells that develop in the thyroid. A small butterfly-shaped gland located below the lower front of the neck is called the thyroid. The thyroid is responsible for controlling metabolism, which helps to regulate the heart rate, blood pressure, body temperature, and weight. Thyroid cancer develops when the cell changes and starts developing in your thyroid. Moreover, there comes a point when the cells are developed more than is required, which causes a tumour in the thyroid. Initially, cancer may not show any signs. However, as it develops, it may show symptoms like neck enlargement, voice changes, and trouble swallowing.

Although it often spreads to the lymph nodes in your neck, it usually grows slowly. You still stand a strong chance of making a full recovery.

  • Follicular Thyroid

The follicular thyroid makes up between 10% to 15% of other cancers. Additionally, this cancer is more harmful than papillary and it passes to other body parts through the bloodstream. Follicular thyroid also develops a rare form of cancer which is known as Hurthle cell cancer which is more aggressive.

  • Medullary Thyroid

According to the American Thyroid Association, this accounts for less than 3% of thyroid cancers. Lymph nodes are typically the site of its propagation. Due to the fact that it produces the hormone called calcitonin, which doctors look for in blood test results, it is more likely to be discovered at an early stage.

  • Anaplastic Thyroid

The prognosis for this type of cancer is worse, and it often develops chemoresistance over time. It is the most uncommon and challenging to treat.
