**What are hot and cold thyroid nodules?** Thyroid nodules are very common and many people are affected by it until the age of 60.... Thyroid nodules have different types, such as cold and hot nodules, and they may be dangerous or harmless.... Changes in swallowing and breathing are among the symptoms of **thyroid nodules**, which we will discuss further.... Thyroid surgery is one of the ways to treat ##pan## thyroid.. **Thyroid nodules What is it?** First, you need to know that the thyroid gland is a fluid-filled or solid mass that forms in the airway in the lower part of the neck. The thyroid gland produces thyroid hormone that helps control many of the body's metabolic functions. People will have thyroid nodules throughout their lives. Nodules that are small in size and located at a distance from sensitive structures such as the trachea are often asymptomatic (meaning patients do not feel them and do not cause any health problems). - Cold and indifferent nodules - Normal warm node Warm nodules are more active than normal thyroid tissue and therefore produce more hormone in comparison...Cold nodules, on the other hand, are tissue masses that have no real ability to produce thyroid hormone compared to normal thyroid tissue...Finally, cold nodules cannot be distinguished from healthy tissue by their ability to produce hormone...Most thyroid nodules are cold nodules (approximately 50-85%), while only 10% of nodules are "hot" and About 5% are warm.. 95% of these nodules are benign and non-cancerous... What is it?** Many thyroid nodules do not cause symptoms. Those that grow too large can compress surrounding structures in the neck. This can sometimes lead to changes in swallowing or breathing. If the nodule produces too much thyroid hormone, symptoms of hyperthyroidism may occur.. This can lead to a fast or irregular heartbeat, nerve weakness and unexplained problems, muscle weakness, weight loss, weight loss.. Thyroid nodules are benign.... Most of the time thyroid blood tests are normal in patients with nodules.... Most thyroid nodules appear as a lump at the base of the neck... so they can be felt or seen in the mirror.... Consult your doctor if you suspect a thyroid nodule.... ### **What is the difference between warm, hot and cold nodes>**. Warm, hot, and cold are the three categories that classify thyroid nodules.. Nodules that produce excess thyroid hormone are classified as warm nodules.. If the nodules are nonfunctioning or appear as holes on the scan, they are cold nodules.. Warm nodules are benign. They are so small that they cannot be seen without imaging tests.. in the US, only 4-7% of the adult population has palpable lumps... However, if cold and indifferent nodules grow, they can cause discomfort and problematic symptoms... stiffness, voice changes, as well as difficulty breathing or swallowing... Hot nodules can cause significant metabolic imbalances and dysregulation of various processes in the body due to increased ability to produce hormones... Overproduction of hormones can lead to hyperthyroidism... Symptoms of hyperthyroidism Thyroid includes anxiety, restlessness, tremors, restlessness, sweating, unusual weight loss, and increased heart rate, etc.. In severe cases, the effects of this disease can even be life-threatening.. It is more dangerous among the elderly who are at risk of developing heart failure. They do....hot nodules are almost always non-cancerous...is it?** Thyroid nodules are usually evaluated with a thyroid ultrasound, which allows the endocrinologist to determine if they are cancerous.. To diagnose a thyroid nodule, sampling with a fine needle aspiration or thyroid surgery can also be performed. Sampling is usually done in the office with the help of ultrasound. The results of thyroid microscopy are classified based on the microscopy of thyroid cells. A biopsy helps the doctor decide if the nodules can be monitored with ultrasound or if tests and surgery are necessary to diagnose them. Treatment options are determined based on the size and type of thyroid nodule. If the nodule is not cancerous, it is not a problem. The endocrinologist may even decide not to treat it. Biopsy ... Despite the fact that the majority of thyroid nodules are non-cancerous, early diagnosis is of utmost importance to clearly classify the nodule and rule out any risk of malignancy. In addition, diagnostic tools help identify the types of nodules (hot, cold, or indifferent) to decide on the most appropriate treatment regimen. Several treatment options are available...surgery and removal of the radioactive nodule as well as the common treatment modality, radiation therapy...but other less invasive treatments are also available for non-cancerous lumps...these treatments include minimally invasive thermal ablation options such as: - Laser ablation - microwave ablation (MWA) Radio Frequency Ablation (RFA) - Non-invasive ecotherapy Dr. Seyed Ahmad Fanai is a thyroid and parathyroid surgeon and a member of the American Thyroid Association. He is known as the golden paw of thyroid surgeon. **What is the difference between a thyroid nodule and a thyroid cyst?**
