A few weeks ago, Peter, a 42-year-old teacher from Nairobi, visited my clinic after noticing a small lump in his neck. “I wasn’t worried at first,” he confessed. “But when my colleague mentioned it might be a thyroid nodule, I couldn’t stop thinking about it. Is it dangerous? Do I need surgery?”
Peter’s story isn’t unique. Thyroid nodules are incredibly common—studies show that nearly half of adults have them, although most remain undetected. While the majority of these nodules are harmless, some may require closer attention. Let’s explore when a thyroid nodule might signal a need for concern.
What Are Thyroid Nodules?
Thyroid nodules are lumps or growths within the thyroid gland, located at the base of your neck. They can vary in size, from tiny spots detectable only through imaging to larger lumps that are visible or palpable.
As a thyroidologist in Nairobi, I frequently see patients with nodules, many of whom are surprised to learn they have them. Most nodules are discovered incidentally during a routine check-up or imaging for another condition.
When to Worry: Signs a Nodule Needs Attention
1. Rapid Growth or Large Size
If your nodule grows quickly or is large enough to be easily visible or cause discomfort, it’s important to consult a specialist. Large nodules can compress nearby structures, leading to symptoms like difficulty swallowing or breathing.
2. Suspicious Features on Ultrasound
Ultrasound is the gold standard for evaluating thyroid nodules. Nodules with irregular shapes, calcifications, or increased blood flow may warrant a closer look, as these features could indicate malignancy.
3. Voice Changes or Persistent Hoarseness
The thyroid is located near the vocal cords, so changes in your voice or persistent hoarseness might indicate a nodule pressing on these structures.
4. Family or Personal History of Thyroid Cancer
A family history of thyroid cancer or a personal history of radiation exposure increases your risk of malignant nodules. Regular monitoring is crucial in such cases.
5. Overactive or Underactive Nodules
Some nodules produce excess thyroid hormones, leading to hyperthyroidism, while others might be linked to hypothyroidism. Both conditions can have significant health implications and should be addressed promptly.
What a Thyroidologist in Nairobi Can Do for You
1. Clinical Evaluation
Your thyroidologist will start with a detailed history and physical examination. They’ll check for signs like swelling, tenderness, or visible lumps.
2. Imaging Studies
Ultrasound provides a detailed view of your thyroid, helping to identify nodules and assess their size, shape, and characteristics.
3. Fine-Needle Aspiration (FNA) Biopsy
If a nodule appears suspicious, an FNA biopsy may be performed. This minimally invasive procedure involves using a thin needle to collect cells from the nodule for further analysis.
4. Treatment Options: Surgery or Minimally Invasive Techniques
While many nodules can be monitored, some patients, like Peter, prefer proactive treatment. One effective option is thyroid microwave ablation (MWA).
Peter’s Outcome: Modern Treatment with Thyroid Microwave Ablation
After his initial consultation and diagnostic tests, Peter’s nodule was found to be benign. However, he preferred to have it treated rather than continue monitoring it. We decided on thyroid microwave ablation (MWA)—a minimally invasive, non-surgical procedure ideal for shrinking or eliminating benign thyroid nodules.
MWA involves inserting a thin probe guided by ultrasound directly into the nodule. The probe emits microwave energy, which generates heat to destroy the abnormal tissue while preserving the surrounding thyroid gland. The procedure is quick, typically lasting 30–60 minutes, and requires minimal recovery time.
For Peter, MWA was the perfect choice. He returned to his routine the following day, relieved to have addressed his concerns without the need for surgery.
Final Thoughts: Don’t Ignore Thyroid Nodules
While most thyroid nodules are harmless, it’s crucial to recognize when they require attention. If you’ve noticed a lump in your neck or are experiencing any related symptoms, consulting a thyroidologist in Nairobi can provide the answers and care you need.
Whether through monitoring or advanced treatments like microwave ablation, there are options tailored to your needs.
