When Should You Worry About Thyroid Nodules?

Key Takeaways

• Most thyroid nodules are noncancerous and never cause a problem, but certain changes are worth having checked promptly.
• Many people do not know they have a thyroid nodule until it is found during a routine exam or an imaging test done for another reason.
• A new lump in the neck, changes in voice, or trouble swallowing are reasons to schedule an evaluation rather than wait it out.
• Rapid growth, a hard or fixed nodule, or a family history of thyroid cancer can raise the level of concern and may call for further testing.
• Dr. Robert Weiss, a board-certified general surgeon at Syracuse Hernia Center, personally evaluates and treats both benign and malignant thyroid nodules, and patients can request an appointment to have a new or existing nodule assessed.

What Is a Thyroid Nodule, and How Is It Usually Found?

A thyroid nodule is a lump that forms within the thyroid gland, the small, butterfly-shaped gland at the base of the neck that helps regulate metabolism, body temperature, and heart rate. Thyroid nodules are common: healthcare providers detect them in about 5% to 7% of adults during a physical exam, and ultrasound imaging finds them in 20% to 76% of adults, since many nodules are too small to feel.

Most people who have a thyroid nodule find out about it by chance, either because a doctor feels it during a neck exam or because it shows up on a scan ordered for an unrelated reason. This is one reason thyroid nodules are worth discussing with a general surgeon in Syracuse, NY, even if the nodule was found incidentally and is not causing any symptoms yet.

Thyroid Nodule Symptoms That Should Not Be Ignored

Most thyroid nodules do not cause any symptoms at all, which is why routine evaluation matters. But when a nodule does produce symptoms, certain ones are worth acting on rather than monitoring on your own:

• A new or growing lump that can be felt or seen at the base of the neck.
• Hoarseness or another change in voice quality.
• Difficulty or discomfort when swallowing.
• Pain in the front of the neck.
• Noticeable swelling of the thyroid gland, known as a goiter.

These thyroid lump symptoms do not automatically mean cancer. Most nodules that cause these symptoms are still benign. But because a small number of nodules with these features turn out to be malignant, they are the symptoms that should move you from 'keep an eye on it' to 'schedule an appointment.'

Risk Factors That May Increase Concern

Certain features and history points raise the likelihood that a nodule needs closer evaluation. More than 90% of detected thyroid nodules in adults are noncancerous, and thyroid cancer is found in roughly 4.0% to 6.5% of cases. The factors below do not mean a nodule is dangerous, but they are the ones your doctor will ask about and weigh together:

Additional factors linked to a higher likelihood of developing thyroid nodules in general include increasing age, a personal or family history of thyroid nodules, and living in an area where iodine intake is low.

How Are Thyroid Nodules Diagnosed and Monitored?

Evaluating a thyroid nodule typically starts with a physical exam and a review of symptoms and history. From there, additional steps may include:

• Thyroid blood tests to check hormone levels, since most nodules do not change how much hormone the thyroid produces.
• Ultrasound imaging to determine whether the nodule is solid or fluid-filled and to track its size and features over time.
• Fine-needle biopsy, in which a small sample of cells is taken from the nodule and reviewed for signs of malignancy.

Many nodules that turn out to be benign are simply monitored with periodic exams and imaging rather than treated right away. This 'watch and wait' approach is a normal and appropriate part of thyroid nodule care, not a sign that something is being missed.

When Surgery or Additional Testing May Be Recommended

Surgery is typically considered when a nodule is confirmed or strongly suspected to be cancerous, when it is large enough to press on the windpipe or esophagus and cause breathing or swallowing problems, or when biopsy results are inconclusive and need to be resolved with tissue removal. At Syracuse Hernia Center, Dr. Weiss personally oversees both the diagnosis and treatment of thyroid lesions, managing the full range from benign nodules to malignant tumors with a focus on minimizing discomfort and recovery time.

Schedule a Thyroid Nodule Evaluation With Syracuse Hernia Center

A new lump in the neck, a change in voice, or difficulty swallowing is worth having evaluated, even though most thyroid nodules turn out to be benign. Dr. Robert Weiss, a board-certified general surgeon with more than 25 years of experience, personally examines and manages every thyroid patient at Syracuse Hernia Center from initial evaluation through treatment.
