What's That Lump in Your Neck? Understanding Thyroid Nodule Tests

The First Line of Defense: Ultrasound

Ultrasound is the go-to initial test for thyroid nodules. It's painless, uses no radiation, and gives doctors a detailed look at the nodule's size, shape, and internal structure. Certain ultrasound features, like irregular edges or tiny calcifications, can raise red flags for potential cancer.

Blood Tests: Checking Thyroid Function

A simple blood test measures thyroid-stimulating hormone (TSH) levels. This helps determine if the nodule is affecting overall thyroid function. Interestingly, a higher TSH level may slightly increase the risk of thyroid cancer, though most nodules are still benign.

The Gold Standard: Fine Needle Aspiration Biopsy

If ultrasound shows suspicious features, the next step is often a fine needle aspiration (FNA) biopsy. This procedure uses a thin needle to collect cells from the nodule for examination under a microscope. While it may sound scary, FNA is usually quick and only mildly uncomfortable.
