Nodule (Definition)

Any growth or deposit in the body or on its surface may be casually termed a nodule until its character is determined by the familiarity of the physician with it or by the results of a biopsy if it is not so obvious. The term is casual ...Read more

Throid nodules. Upper right lobe hot, lower right lobe cold 3.4cm. Does that mean I have hyper and hypo thyriodism at the same time?

Throid nodules. Upper right lobe hot, lower right lobe cold 3.4cm. Does that mean I have hyper and hypo thyriodism at the same time?

No, the activity: of individual nodules on a thyroid scan may not, in and of themselves, imply hyper or hypothyroidism, which are diagnoses based on systemic symptoms and blood levels. Certainly, however, an autonomous hot nodule could result in hyperthyroidism. Cold nodules have a higher chance of malignancy(although still relatively low), and biopsy may be indicated. ...Read more

Are cold thyroid nodules cancerous?

Are cold thyroid nodules cancerous?

Only occassionally: While almost all thyroid cancers are cold, so are most benign nodules. If the nodule is hot, it is extremely rare for it to be cancer. If it is cold and looks suspicious on an ultrasound performed or at least interpreted by a very experienced clinician, it should be biopsied to see if surgery is necessary. ...Read more

Thyroid nodules (hot or cold)? How can you tell which is which?

Images: "hot" or "cold" is a term related to the appearance on nuclear medicine imaging. A "hot" nodule is one that is too active, and secretes hormone, but benign. A cold nodule takes up less tracer. About 20% of these are malignant, and so they are biopsied. Cysts will also show up cold as they are fluid rather than tissue, so this study should be interpreted along side an ultrasound. ...Read more

Are cold nodules in thyroid with increase vascularity always malignants?

Definitely not: They are much more often benign, but should probably be biopsied, particularly if 1 cm or greater, they enlarge, serum thyroglobulin is elevated, etc. ...Read more

Can a thyroid nodule be determined hot or cold after it's removed?

No: You can tell if something is "hot" or "cold" on a thyroid scan. We use it to decide what to do with the nodule. Once it's removed, it doesn't matter if it's hot or cold. You will not be able to tell with certainty once it's removed. ...Read more

Thyroid biopsy cold nodule showed Follicular cells 2x4cm. Being sent out for generic testing? Will this show if it's benign?

Thyroid nodules: This is a good question and not totally resolved in the thyroid cancer field. On needle aspiration, it is often impossible to distinguish between a follicular adenoma (benign) or follicular cancer. The genetic tests theoretically help make the distinction. But they are not perfect. Many doctors would send you to a good thyroid surgeon and remove a 2x4 cm thyroid nodule with follicular cells. ...Read more

What are the chances of "cold" solid nodule being thyroid cancer?

What are the chances of "cold" solid nodule being thyroid cancer?

Thyroid nodule: Presumably "cold" means it did not take up radioiodine. Together, the chances of this being a cancer are quite low. There are many reasons for low uptake. Hashimotos can look like this. A multinodular goiter can have many hot/warm/cold areas. A cyst. How big is it? Small nodules (. ...Read more

Thyroid scan: You can't tell if a nodule is hot or cold for sure on a thyroid ultrasound. A test called thyroid uptake and scan is what's needed to determine if a nodule is hot or cold. ...Read more
