What are thyroid nodules?
Thyroid nodules are lumps in the thyroid gland caused by aberrant growths of thyroid tissue and cells. Thyroid hormone, which is released by the thyroid gland in the neck, aids in regulating the body’s metabolism.
Thyroid nodules must be assessed in order to treat thyroid cancer in its early stages because most of them are benign (non-cancerous), but some are.
What are the symptoms?
The majority of thyroid nodules are discovered during routine exams or by CT scans or other comparable imaging tests, and they typically don’t cause any symptoms. While the majority of thyroid nodules do not function, some do, and this leads to hyperthyroidism.If a thyroid nodule is large enough, it may show up as a lump on the neck or cause breathing and swallowing difficulties by obstructing the windpipe.
What causes thyroid nodules?
The cause of thyroid nodules is not always obvious or well understood. Since iodine is frequently added to salt and other foods, it is rare for certain nodules to be linked to an iodine deficiency. Thyroid nodules are more likely to develop in people with the autoimmune disease Hashimoto’s thyroiditis.Thyroid cysts, goitre, and an overabundance of thyroid tissue can all result in thyroid nodules. The cause of growths and swelling, however, is not always evident.
How can they be prevented?
It is impossible to avoid thyroid nodules. There are tests that can identify whether a person has a thyroid nodule, but you should always consult a physician before doing so.
How are thyroid nodules treated?
The course of treatment for thyroid nodules is determined by the nodule’s functioning and whether it is malignant or benign.
A thyroid nodule needs to be surgically removed if it is malignant. Generally speaking, thyroid cancer is curable and treatable.If the patient experiences discomfort due to a large thyroid nodule, surgery may also be necessary. If the nodule is actively secreting hormones, it may also be removed.
Treatment might not be required if a thyroid nodule is benign; instead, it will be closely watched. Regular physical examinations and thyroid function tests will be conducted to ensure the nodule remains benign. Medication, radioactive iodine therapy, or occasionally surgery can be used to treat thyroid nodule production of thyroid hormones.
