Everything you need to know about this condition
What is Neoplasm of uncertain behavior of thyroid gland?
A neoplasm of uncertain behavior of the thyroid gland is a condition where a tumor grows in the thyroid gland, but it's unclear if it's cancerous or not. This type of tumor is also known as a "thyroid tumor of uncertain malignant potential" or "TUMP". According to WHO guidelines, TUMPs account for about 5-10% of all thyroid tumors. If you've been diagnosed with this condition, it's essential to understand that it's not necessarily cancer, but it does require close monitoring and possibly treatment.

- Genetic mutations: Certain genetic mutations, such as those that occur in familial adenomatous polyposis (FAP), can increase your risk of developing thyroid tumors.
- Radiation exposure: Exposure to radiation, especially during childhood, can increase your risk of developing thyroid tumors.
- Family history: If you have a family history of thyroid tumors or thyroid cancer, you may be at higher risk.
- Age: TUMPs are more common in people over the age of 40.
- Sex: Women are more likely to develop TUMPs than men.
