The normal thyroid weighs approximately 15 to 25 g, with each lobe 4 to 6 cm in length and 1.3 to 1.8 cm in thickness. The isthmus measures less than 4 to 5 mm.When should you worry about thyroid nodules?
If the thyroid nodules are causing symptoms such as shortness of breath, hoarseness of voice, and pain, your doctor may recommend that you undergo a thyroidectomy. This is a surgical procedure that involves the removal of part or all of the thyroid gland. A thyroidectomy may also be recommended if you have a single toxic nodule.Are isthmus nodules dangerous?
Recent research has found that nodules in the thyroid isthmus pose a greater risk of malignancy than nodules in the lobes. Nodules in the lower portion of the lobes are believed to be at least risk for cancer. 4What percentage of thyroid nodules are cancerous?
Doctors are concerned about thyroid nodules, because they can sometimes be cancerous. Thyroid cancer is found in about 8 percent of nodules in men (or 8 out of 100) and in 4% of nodules in women. Thus, about 90% of all thyroid nodules are benign (non-cancerous).
