What is Thyroid cancer

Thyroid cancer is a malignancy that originates in the thyroid gland, a butterfly-shaped endocrine organ located at the base of the neck that regulates metabolism. While most forms of thyroid cancer are highly treatable and have excellent long-term survival rates, they require specialized medical management to ensure the gland's hormonal output is balanced and the cancer is effectively addressed.

What are the main types of thyroid cancer?

Thyroid cancer is classified based on the specific type of cells from which the tumor develops. The primary subtypes include:

• Papillary thyroid cancer: The most common form, accounting for approximately 80% of all cases.


• Follicular thyroid cancer: A less common form that, along with papillary, is often referred to as "differentiated" thyroid cancer.


• Medullary thyroid cancer: Originates in C-cells and can sometimes be linked to genetic syndromes.


• Anaplastic thyroid cancer: A rare, aggressive, and fast-growing form that requires immediate, intensive intervention.

Who is typically affected by thyroid cancer?

Thyroid cancer is diagnosed in approximately 44,000 people in the United States annually. It is notable for its gender distribution, as it is diagnosed roughly three times more often in women than in men. While it can occur at any age, the average age at diagnosis is 51, making it a condition that frequently affects younger and middle-aged adults compared to many other solid-tumor malignancies.

How does thyroid cancer develop?

The pathophysiology of thyroid cancer involves genetic mutations within the thyroid follicular cells, which cause them to grow and divide uncontrollably. These mutations can be triggered by external factors, such as high levels of radiation exposure to the neck (particularly in childhood), or inherited genetic predispositions. Unlike many other cancers, the prognosis for most patients with thyroid cancer is very positive, provided the disease is identified and treated early by an endocrinologist or endocrine surgeon.

Next steps

• Consult with an endocrinologist to discuss any persistent neck lumps, hoarseness, or swallowing difficulties.

• Request a referral to a high-volume endocrine surgical center if a diagnosis is suspected.
