Could it be more than “just a thyroid nodule”?
Most thyroid nodules are benign — but some need closer evaluation. 🩺

⚠️ Warning signs of thyroid cancer can include:
🔹 A firm lump in the neck
🔹 Hoarseness or voice changes
🔹 Trouble swallowing or breathing
🔹 Swollen lymph nodes
🔹 A history of neck radiation or thyroid cancer in the family

Not all nodules cause symptoms — that’s why ultrasound and biopsy are so important.

The good news? ✅
When thyroid cancer is caught early, it’s highly treatable.

If you’ve noticed changes in your neck or voice, or if you’ve been told you have a thyroid nodule, we’re here to help you find answers.

Hashimoto’s and Graves’ disease are both autoimmune thyroid conditions — but they affect your body in very different ways. 🧬

🔹 Hashimoto’s = underactive thyroid (hypothyroidism)
🔹 Graves’ = overactive thyroid (hyperthyroidism)

While both involve the immune system attacking the thyroid, the symptoms, lab results, and treatments are quite different.

Does RFA completely eliminate thyroid nodules? 🤔

Great question — and the answer is: not always, but that’s not the goal.
🎯 The goal of Radiofrequency Ablation (RFA) is to shrink the nodule enough to relieve symptoms, improve appearance, and avoid surgery.

📉 Most nodules shrink by 60–90% over time.
🧘‍♀️ Patients often feel relief in pressure, swallowing, or voice changes.
👕 No scar. No hospital stay. Just results.

And if the nodule continues to grow or causes problems later?
🔁 RFA can be repeated safely.
