Is a 2 cm thyroid nodule big?

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 size thyroid nodule should be removed?

Some surgeons recommend thyroidectomy for nodules ≥4 cm even in the setting of benign FNAC, due to increased risk of malignancy and increased false negative rates in large thyroid nodules [12,13,14,15]. Even more aggressive surgeons use a threshold of 3 cm [16].

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).

Can you tell if a thyroid nodule is cancerous from an ultrasound?

An ultrasound may show your doctor if a lump is filled with fluid or if it's solid. A solid one is more likely to have cancerous cells, but you'll still need more tests to find out. The ultrasound will also show the size and number of nodules on your thyroid.

What size nodule should be removed?

What is a thyroid ultrasound?

• Thyroid ultrasound. A thyroid ultrasound is an imaging method to see the thyroid, a gland in the neck that regulates metabolism (the many processes that control the rate of activity in cells and tissues). Ultrasound is a painless method that uses sound waves to create images of the inside of the body.
