RGS Health Care

Thyroid cancer is a type of malignant tumor affecting the thyroid gland located in the neck. There are different types of thyroid cancers, which are distinguished by the cells they originate from and their behavior. It is essential for clinicians to be familiar with each type to analyze treatment options effectively, such as radiofrequency ablation, which has been shown to be a promising approach for specific cases of differentiated thyroid cancer, like PTMC radiofrequency ablation.

Papillary thyroid cancer (PTC) is the most common type, accounting for approximately 80% of all thyroid cancer cases. It develops from the follicular cells in the thyroid gland and typically grows slowly. PTC often forms finger-like projections called papillae, giving it its name. Although it usually has an excellent prognosis, more aggressive variants of papillary thyroid cancer exist, like the tall cell and insular variants.

Follicular thyroid cancer (FTC), the second most common type, also originates from follicular cells. It represents around 10-15% of all thyroid cancer cases. FTC tends to grow slowly and is less likely to spread to the lymph nodes compared to PTC. However, it has a higher risk of spreading to distant organs, such as the lungs or bones.

Medullary thyroid cancer (MTC) accounts for about 4% of thyroid cancer cases. It arises from parafollicular cells, also called C cells, which produce the hormone calcitonin. MTC can occur sporadically or as part of genetic syndromes, such as multiple endocrine neoplasia type 2 (MEN2). Early detection and treatment are critical, as MTC can be aggressive and challenging to manage.


Anaplastic thyroid cancer (ATC) is a rare and highly aggressive form of thyroid cancer, representing less than 2% of cases. It often affects older adults and can grow rapidly, invading nearby structures and spreading to distant organs. Due to its aggressive nature, ATC carries a poor prognosis with limited treatment options.

Differentiated thyroid cancers (DTC) include both PTC and FTC and are generally easier to treat due to their ability to take up iodine. This characteristic allows for the use of radioactive iodine therapy in managing these cancers. In contrast, MTC and ATC are considered non-differentiated primary thyroid cancers only, making them more challenging to treat using iodine therapy.

In specific cases, such as small, localized papillary thyroid microcarcinomas (PTMC), radiofrequency ablation of thyroid, has emerged as a promising minimally invasive treatment option. This approach uses high-frequency radio waves to generate heat, destroying the cancer cells and preserving the surrounding healthy thyroid tissue.
