Thyroid Nodules: Causes, Symptoms & Expert Treatment in Chennai

What are Thyroid Nodules? Causes, Symptoms, and Treatment Options with Dr. Vidhyadharan Sivakumar at THANC Hospital, Chennai

Thyroid nodules are lumps that develop within the thyroid gland, a butterfly-shaped gland located at the base of your neck. While the term "nodule" might sound alarming, the vast majority of thyroid nodules are benign (non-cancerous). However, it's crucial to have them evaluated by an experienced head and neck surgeon to rule out malignancy and determine the best course of action. As Clinical Director and Senior Consultant at THANC Hospital in Chennai, I, Dr. Vidhyadharan Sivakumar, have extensive experience in diagnosing and treating thyroid nodules.

The good news is that most thyroid nodules don't cause any symptoms and are often discovered incidentally during a routine physical exam or imaging test for another condition. However, larger nodules can sometimes lead to noticeable symptoms that require prompt medical attention. Understanding the thyroid nodules causes symptoms treatment is essential for early detection and effective management.

Understanding Thyroid Nodules: Causes and Risk Factors

The exact cause of thyroid nodules is often unknown, but several factors can contribute to their development:

• Iodine Deficiency: A lack of iodine in the diet can lead to thyroid enlargement (goiter) and the formation of nodules. While iodine deficiency is less common in developed countries due to iodized salt, it can still be a factor in certain populations.

• Hashimoto's Thyroiditis: This autoimmune condition causes chronic inflammation of the thyroid gland, which can increase the risk of nodule formation.

• Family History: A family history of thyroid nodules or thyroid cancer can increase your risk.

• Age: Thyroid nodules become more common with age.

• Radiation Exposure: Exposure to radiation, especially during childhood, can increase the risk of thyroid nodules and thyroid cancer.

• Multinodular Goiter: This condition involves the enlargement of the thyroid gland with multiple nodules.

In my practice, I often see patients concerned about the cause of their thyroid nodules. It's important to remember that having one or more of these risk factors doesn't guarantee that you'll develop thyroid nodules, but it's crucial to be aware of them and undergo regular check-ups if you're at higher risk.

Recognizing the Symptoms of Thyroid Nodules

Many thyroid nodules are asymptomatic, meaning they don't cause any noticeable symptoms. These nodules are often discovered incidentally during a routine physical exam or imaging test performed for another reason. However, when symptoms do occur, they can vary depending on the size and location of the nodule:

• Palpable Lump: The most common symptom is a lump in the neck that you can feel when you touch your throat.

• Difficulty Swallowing (Dysphagia): Larger nodules can compress the esophagus, making it difficult or uncomfortable to swallow.

• Hoarseness: Nodules that affect the recurrent laryngeal nerve, which controls the vocal cords, can cause hoarseness or a change in your voice. This is a critical symptom that requires immediate evaluation. This is an area of specific expertise at our Voice Clinic at THANC Hospital.

• Neck Pain: In rare cases, nodules can cause pain in the neck, jaw, or ear.

• Breathing Difficulties: Large nodules can compress the trachea (windpipe), leading to difficulty breathing, especially when lying down. Airway Management is a key focus at THANC Hospital.

• Hyperthyroidism Symptoms: If the nodule is "hot" (overactive), it can produce excess thyroid hormone, leading to symptoms of hyperthyroidism such as:

  • Rapid heartbeat
  • Weight loss
  • Anxiety
  • Tremors
  • Sweating

• Hypothyroidism Symptoms: Rarely, nodules can damage the thyroid gland, leading to hypothyroidism, with symptoms such as:

  • Fatigue
  • Weight gain
  • Constipation
  • Dry skin
  • Feeling cold

If you're experiencing any of these symptoms, early consultation is crucial. Book an appointment with Dr. Vidhyadharan at THANC Hospital, Chennai.

Diagnosing Thyroid Nodules: A Comprehensive Approach

A thorough evaluation is essential to determine the nature of a thyroid nodule and rule out malignancy. The diagnostic process typically involves:

1. Physical Examination: I will carefully examine your neck to assess the size, location, and consistency of the nodule.

2. Thyroid Function Tests: Blood tests to measure thyroid hormone levels (TSH, T4, and T3) to determine if your thyroid gland is functioning properly.

3. Ultrasound: This imaging technique uses sound waves to create a detailed picture of the thyroid gland and the nodule. Ultrasound can help determine the size, shape, and internal characteristics of the nodule, as well as identify any suspicious features.

4. Fine Needle Aspiration (FNA) Biopsy: This is the most important test for evaluating thyroid nodules. During FNA, a thin needle is inserted into the nodule to collect a sample of cells, which are then examined under a microscope by a pathologist. FNA can determine whether the nodule is benign, suspicious, or malignant.

   • Molecular Testing: In some cases, particularly when FNA results are inconclusive, molecular testing may be performed on the FNA sample to analyze the genetic makeup of the cells. This can help further clarify the risk of malignancy.

5. Thyroid Scan (Radioiodine Scan): This imaging test is used to determine if a nodule is "hot" (overactive) or "cold" (non-functioning). Hot nodules are rarely cancerous.

6. CT Scan or MRI: These imaging tests may be used in certain cases to evaluate the size and extent of the nodule, especially if it's large or located in a difficult-to-access area.

Thyroid Nodule Treatment Options: A Personalized Approach

The treatment for thyroid nodules depends on several factors, including the size and characteristics of the nodule, the presence of symptoms, and the risk of malignancy.

As an experienced head and neck surgeon, I believe in a personalized approach to thyroid nodule treatment. I carefully consider each patient's individual circumstances and preferences when developing a treatment plan.

Surgical Options for Thyroid Nodules: Expertise at THANC Hospital

When surgery is necessary, I perform both partial and total thyroidectomies. My goal is to remove the nodule while preserving as much of the healthy thyroid tissue as possible and minimizing the risk of complications. At THANC Hospital, we use advanced surgical techniques and monitoring to ensure the best possible outcomes for our patients.

• Minimally Invasive Thyroidectomy: In select cases, I may be able to perform a minimally invasive thyroidectomy, which involves making a smaller incision and using specialized instruments to remove the nodule. This can result in less pain, a shorter hospital stay, and a smaller scar.

• Intraoperative Nerve Monitoring: During thyroid surgery, I use intraoperative nerve monitoring to protect the recurrent laryngeal nerve, which controls the vocal cords. This helps to minimize the risk of hoarseness after surgery.

• Parathyroid Hormone Monitoring: We also monitor parathyroid hormone levels during surgery to help prevent hypoparathyroidism (calcium deficiency).

THANC Hospital is a leading center for head and neck surgery in Chennai, and we are committed to providing our patients with the highest quality of care. Our team has extensive experience in performing thyroid surgery, and we use the latest techniques and technology to ensure the best possible outcomes.

Life After Thyroid Nodule Treatment: What to Expect

The long-term outlook after thyroid nodule treatment depends on the underlying cause of the nodule and the type of treatment received.

• Benign Nodules: If the nodule is benign and doesn't cause any symptoms, you may not need any further treatment after the initial evaluation. However, regular monitoring with physical exams and ultrasound is recommended to ensure that the nodule doesn't grow or develop any suspicious features.

• Surgery: If you undergo thyroid surgery, you may need to take thyroid hormone medication (levothyroxine) for the rest of your life to replace the thyroid hormone that your body is no longer producing. Regular blood tests are needed to monitor your thyroid hormone levels and adjust the dosage of medication as needed.

• Thyroid Cancer: If the nodule is cancerous, you will need to undergo further treatment, which may include surgery, radioactive iodine therapy, and/or external beam radiation therapy. The long-term outlook for thyroid cancer is generally very good, especially when it's detected early and treated appropriately.

Patients often ask me about the potential side effects of thyroid surgery. While complications are rare, they can include hoarseness, hypoparathyroidism, and bleeding. At THANC Hospital, we take every precaution to minimize the risk of complications and ensure the best possible outcome for our patients.
