Final answer:
Thyroid adenomas are noncancerous tumors that develop in the thyroid gland due to a mutation found within the tumor tissue, not inherited.
Step-by-step explanation:
The subject of this question is Biology.
Thyroid adenomas are noncancerous tumors that develop in the thyroid gland. The mutation causing thyroid adenomas is found within the tumor tissue, but it is not inherited. This means that the mutation occurs randomly in the cells of the thyroid gland. The mutation may be caused by various factors, such as exposure to radiation or certain chemicals.
For example, excessive exposure to ionizing radiation, such as from medical treatments or nuclear accidents, can increase the risk of developing thyroid adenomas. Additionally, some specific genetic mutations have been associated with a higher risk of developing these tumors.
