Thyroid Nodule Treatment in Lucknow
Thyroid nodules are lumps that occur in the thyroid gland. Thyroid nodules may be solid, cystic (fluid filled), or a combination of both and can develop in any location within the thyroid gland. At least 85% of thyroid nodules are benign thus thyroid cancer accounts for only a small percentage of all thyroid nodules. Thyroid nodules are generally not considered a serious condition and most often detected without producing any symptoms whatsoever.
Thyroid nodules are most commonly found when a doctor examines a patient’s neck, feeling the thyroid gland. Sometimes thyroid nodules are found when a patient gets x-rays or scans of the neck for some other reason. Sometimes it is a screening x-ray or scan for carotid arteries or neck pain that shows nodules in the thyroid. Thyroid nodules that are large, develop in women with thin necks, or are present in the middle portion of the thyroid gland (called the isthmus) may be visible and discovered as a lump in the neck.
Thyroid Nodule Symptoms: Uncommon but can Happen:
Thyroid nodule patients usually have no symptoms, but when they do have symptoms they are most commonly:
Thyroid nodules may also rarely produce the thyroid hormone, thyroxine, in excess. This is uncommon but the reason why all patients with thyroid nodules should have a blood test for thyroid stimulating hormone (TSH). Thyroid nodules that produce extra thyroid hormone can cause symptoms of hyperthyroidism which include:
Thyroid Nodules: Potential Causes
Several conditions may cause or predispose to the development of thyroid nodules including:
Overgrowth of normal thyroid tissue
The reason why these thyroid nodules occur is not well understood. These thyroid nodules are commonly called follicular adenomas or thyroid adenomas. (the follicular cell is a normal appearing thyroid cell). Follicular adenomas are clearly not cancerous and are not worrisome and do not require removal except if they are symptomatic due to their size. The rare follicular adenoma or thyroid adenoma will overproduce thyroid hormone and be the cause of hyperthyroidism. For some reason these excessive thyroid hormone producing adenomas lose their ability to be regulated by the pituitary glands production of Thyroid Stimulating Hormone (TSH).
Thyroid cysts are fluid filled cavities caused by degenerating thyroid adenomas, congenital cysts, or overproduction of a fluid produced by the thyroid called colloid.
Inflammatory diseases of the thyroid (called thyroiditis)
Hashimoto’s thyroiditis or Hashimoto’s disease is a chronic inflammatory condition of the thyroid gland caused by an autoimmune event where the patient develops antibodies to thyroglobulin (a normal protein produced by the thyroid gland). Long standing Hashimoto’s thyroiditis is frequently associated with diseased thyroid hormone production call hypothyroidism. Hashimoto’s thyroiditis may also be associated with thyroid pseudo-nodule formation. These pseudo nodules are not concerning thyroid nodules. Pseudo nodules found on ultrasound in thyroiditis patients will come and go based upon unknown issues.
