The thyroid gland is a gland that we don’t usually care about, but it is often unknowingly problematic and not easily detected by everyone, often found only during medical checkups, but many patients reflect that it doesn’t hurt and doesn’t need to be managed, right? Today I have listed the cases of thyroid nodules that require surgical intervention, not “ignored”, because it may become a “cancer” that can destroy you at any time. “It may become a cancer that can destroy you at any time. 1.Single solid nodule over 1 cm in size. 2.Single solid nodule less than 1 cm but with calcification or abnormal blood flow or enlarged lymph nodes. 3.Single cyst more than 2-3 cm. 4.Multiple nodules in which the largest nodule is more than 2 cm or nodules with calcification or abnormal blood flow or lymph node enlargement. 5, Thyroid nodule with previous history of neck radiation exposure or treatment. 6, Age less than 20 years old or greater than 70 years old. 7, Male patients with thyroid nodules. 8.Patients with retrosternal thyroid enlargement. 9.Patients with sudden increase in thyroid nodules recently. 10.Thyroid nodules with pressure, voice change, swallowing difficulty and irritating cough.
