Nodules >1 cm were considered benign if no abnormal cells (benign cytology) were found on an adequate FNA, if no evidence of cancer was found on histologic examination of the resected nodule, if thyroid scintigraphy indicated the nodule functioned autonomously, or if cystic, there was greater than a 50% reduction in …

If the TSH is normal or high, then most individuals with a thyroid nodule larger than 1.0 to 1.5 cm (1/2 inch) in diameter as well as those with a suspicious goiter need to have a fine needle aspiration biopsy to obtain thyroid cells for cytologic evaluation by an expert pathologist.

What size thyroid nodule is worrisome?
The nodules in 5% of each size group were classified as malignant. Six percent of the nodules 1 to 1.9 cm were considered suspicious, as were 8 to 9% of nodules in the larger size groups. Based on surgical pathology, 927 of 7348 nodules (13%) were cancers.
What is the average size of a thyroid nodule?
The average sizes of the nodules were 3.17±1.76 cm (between 0.4cm and 10cm). In terms of size, 115(68.9%) cases had nodules in size of 4cm, and 52 (31.1%) cases had nodules in size of ≥4cm.
What makes a thyroid nodule suspicious?
For the U.S. population, the lifetime risk of developing thyroid cancer is 1.1 percent. When a thyroid nodule is suspicious – meaning that it has characteristics that suggest thyroid cancer – the next step is usually a fine needle aspiration biopsy (FNAB).
How painful is a thyroid biopsy?
A needle biopsy is less invasive than open and closed surgical biopsies, both of which involve a larger incision in the skin and local or general anesthesia. Generally, the procedure is not painful and the results are as accurate as when a tissue sample is removed surgically.

How often should you biopsy thyroid nodules?
Abstract. Background: In the case of a nondiagnostic thyroid fine-needle aspiration (FNA) biopsy result, recent guidelines from the Bethesda system recommend repeat thyroid FNA after 3 months to prevent false-positive results.
How is a nodule removed from thyroid?
For a thyroid lobectomy, surgeons remove one lobe of the thyroid and the isthmus. A doctor may also use a lobectomy to manage a single toxic nodule that is causing hyperthyroidism. A lobectomy is also used to remove a thyroid nodule that might contain cancer.
Can stress cause thyroid nodules?
Stress alone will not cause a thyroid disorder, but it can make the condition worse. The impact of stress on the thyroid occurs by slowing your body’s metabolism. This is another way that stress and weight gain are linked.

The risk of cancer increased to 15% of nodules greater than 2 cm. In nodules that were larger than this 2 cm threshold, the cancer risk was unchanged. However, the proportion of rarer types of thyroid cancer such as follicular and Hurthle cell cancer did progressively increase with . increasing nodule size.
What foods to avoid if you have thyroid nodules?
- soy foods: tofu, tempeh, edamame, etc.
