Do solid benign thyroid nodules grow quickly? and could you have normal tsh levels with a solid benign nodule on the thyroid?

Depends: It is possible to have normal TSH levels, and it is also possible to have abnormal TSH levels. Benign nodules may or may not change in size. Anytime there is a change in nodule size (especially a rapid growth) anywhere on the body, it's good to have it reevaluated by a doctor.

Thyroid nodules: Thyroid nodules are divided in hot or cold by thyroid nuclar scan. Cold nodules are the one's than in some % may be cancerous and require biopsy. Any tissue that grows too fast is suspicious for malignancy. We also dive thyroid. Ovules in "functional" ( with changes in the thyroid hormones) and "not functional" ( with normal thyroid dunction tests).

Nodules: Growth of thyroid nodules may represent malignancy. The only way to really know is to perform fna biopsy. Many patients with solid thyroid nodules will have normal tsh. Thyroid scans are generally no longer thought to be useful in distinguishing between benign and malignant nodules. Rai thyroid scans should be ordered in patients with suspected hyperthyroidism, not routinely for all patients.
