A thyroid nodule was found on my neck during an unrelated CT scan. Should I have the nodule evaluated?

An incidental thyroid nodule (ITN) is a solid or liquid-filled lump not previously detected by a doctor, but identified by an imaging scan. These nodules are very common, and frequently detected in MRI, CT and other non-thyroid ultrasound scans. While something like this can be a source of anxiety, it’s important to remember that the vast majority of nodules are benign and don’t need intervention. However, a visit to your doctor is still recommended, as thyroid nodules can be dangerous. Your doctor may order a thyroid ultrasound to detect any signs of cancer.

Luckily, ultrasound scan is very safe, consistent and informative in the management of thyroid nodules. Like a mammogram or PAP smear, a thyroid ultrasound is structured and repeatable. It’s a surveillance method that allows us to keep an eye on the nodule without needing to do a biopsy or surgery. (All you’ll need to do is make a simple trip to the radiologist during your lunch break.)

If further evaluation of a suspicious nodule is needed, we use a unified system of reporting called Thyroid Imaging Reporting and Data System (TI-RADS). While nodules with higher suspicion may need biopsy or surgery, those that have low likelihood of malignancy may only need monitoring and some follow-up.

Having a personalised plan with your surgeon is key. It should set clear parameters so that the patient is not overly worried if they don’t need to be.
