If you’ve discovered a lump in your neck, we’re here to provide clarity and comprehensive care. Dr. Manish Taneja, our vascular expert, specializes in cutting-edge treatments for thyroid nodules, combining expertise with personalized support.
Introduction to Thyroid Nodules
The thyroid gland is a butterfly shaped gland in the neck just below the voice box. Thyroid gland produces hormone that is required for our metabolism with under or over hormone secretion both causing physical problems.
Thyroid nodules are abnormal lumps (growths) within the thyroid gland. This is a very common condition seen in approximately 30% of adults. These are more commonly seen in females. There can be single or multiple thyroid nodules.
Most thyroid nodules are benign growths. They usually are non-functioning and do not affect function of the thyroid gland.
Thyroid Nodules Symptoms
Thyroid nodules do not commonly cause symptoms however, you’re likely to experience some of these symptoms when thyroid nodules begin to grow:
- Pain from nodule bleeding or inflammation
- Breathing and (or) swallowing difficulties
- Hoarseness
- Hyperthyroidism
- Weight gain or loss
- Heat intolerance
- Muscle weakness
Prevention, Causes, and Risk Factors
Thyroid nodules are of various forms and sizes, from small non-cancerous ones, hyperthyroidism, or large cysts . Most may not be serious, but it is best to receive an evaluation to assess the severity and nature of the thyroid nodule. While exact causes are unknown, nodules can grow due to following factors:
Either iodine excess, deficiencies, thyroid autoimmunity
- Thyroid conditions such as hyperthyroidism
- Family history of thyroid nodules
Types of Thyroid Nodules
This unusual lump in or on the thyroid gland at the front of the neck are usually caused by the abnormal overgrowth of cells in the gland. Either solid or filled with fluid, there are different types of thyroid nodules:
- Non cancerous Thyroid Nodules
- Toxic Nodules (Hyperthyroidism)
- Multinodular Goiter
- Thyroid Cysts
Thyroid Nodules Diagnosis
The main goals when assessing a thyroid nodule are to determine if it is cancerous and to check thyroid function. Normally, an ultrasound scan followed by fine needle biopsy (FNAC) is done to decide on nature of the thyroid nodules. Tests to help evaluate and diagnose a thyroid nodule may include:
Physical exam: Your doctor will assess the size and consistency of the nodule. You may need to swallow repeatedly while the provider examines your thyroid.
Thyroid function tests: A thyroid blood test checks the levels of thyroid hormones in your blood and whether your thyroid is functioning properly.
Ultrasound: A thyroid ultrasound will produce images of your thyroid gland. It will also provide more information about the shape and structure of the nodules.
Fine-needle biopsy: A very thin needle is used to remove a sample of cells from the nodules. The samples are then sent to the lab for evaluation to determine whether cancer is present.
Thyroid scan: A small amount of radioactive iodine is administered either through injection or orally. A special camera is then used to take pictures of your thyroid.
Treatment Options
- Monitor with regular ultrasound scan and biopsy if required.
- Surgical resection of partial or whole thyroid gland
- Radiofrequency ablation of thyroid nodules
One of the latest techniques introduced for treating these patients is radiofrequency ablation (RFA) of thyroid nodules. This is a minimally invasive technique that involves introducing a small special needle under ultrasound guidance into the nodule. Heat energy is applied to the nodule using this needle with destruction of cells from within. The nodules gradually shrink in size on follow-up and become a scar tissue within the normal thyroid gland.
The Advantages of RFA of Thyroid Nodules
The major advantages of the technique are as below.
- It is done as day surgery procedure under light sedation.
- It takes about 45 minutes to one hour to complete the entire procedure.
- Patients are discharged the same day.
- Normal thyroid tissue adjacent to the nodule is preserved.
- It does not affect thyroid function.
- Multiple nodules can be treated at same time.
- The treated nodules do not regrow again.
- No surgical scar with needle mark on the skin.
- Quick recovery and back to full activity and normal lifestyle.
- The technique is suitable to treat even large thyroid nodules.
In conclusion, thyroid nodule comes about as a result of growths on the thyroid. Find out how thyroid nodule radiofrequency ablation can help you in a minimally invasive way.
