Can an ultrasound tell if a thyroid nodule is cancerous?

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.
