An autonomous thyroid nodule or "hot nodule" is one that has thyroid function independent of the homeostatic control of the HPT axis (hypothalamic–pituitary–thyroid axis). According to a 1993 article, such nodules need to be treated only if they become toxic; surgical excision (thyroidectomy), radioiodine therapy, or both may be used. [32]
A thyroid scan, performed often in conjunction with a radioactive iodine uptake test may be used to determine whether a nodule is hyperactive [26] which may help to make a decision whether to perform a biopsy of the nodule. [27] Measurement of calcitonin is necessary to exclude the presence of medullary thyroid cancer.
Radioiodine therapy with iodine-131 can be used to shrink the thyroid gland (for instance, in the case of large goiters that cause symptoms but do not harbor cancer—after evaluation and biopsy of suspicious nodules has been done), or to destroy hyperactive thyroid cells (for example, in cases of thyroid cancer). The iodine uptake can be high ...
Colloid nodules may be initially identified as an unspecified kind of thyroid nodule. Follow-up examinations typically include an ultrasound if it is unclear whether or not there really is a nodule present. Once the presence of a nodule has been confirmed, the determination of the kind of thyroid nodule is done by fine needle aspiration biopsy. [7]
Thyroid cancer affects tens of thousands of people per year, and the majority are women. Of the 44,000 people who will likely be diagnosed with thyroid cancer this year, more than 31,000 will be ...
If the nodule is benign, patients may receive thyroxine therapy to suppress thyroid-stimulating hormone and should be reevaluated in six months. [2] However, if the benign nodule is inhibiting the patient's normal functions of life; such as breathing, speaking, or swallowing, the thyroid may need to be removed.
Serena Williams’ husband, Alexis Ohanian, is on the mend after undergoing surgery on his thyroid. “After tracking some suspicious nodules on my thyroid for the last 4 years, I recently got ...
Thyroid function tests will help reveal whether the nodule produces excess thyroid hormones. A radioactive iodine uptake test can help reveal the activity and location of the cancer and metastases. [67] [69] Thyroid cancers are treated by removing the whole or part of thyroid gland. Radioactive Iodine-131 may be given to radioablate the thyroid.
