Thyroid nodules can be examined in the following ways: First, physical examination, which includes frontal and back methods, can reveal an enlarged thyroid gland or thyroid nodules by examining the thyroid gland by hand and looking at both sides of the thyroid gland. Benign nodules are not very large and can be found in the thyroid gland and move with swallowing without pressure or pain. Malignant thyroid nodules that invade the surrounding tissues have a hard texture and are very immobile. Secondly, ultrasound examination can reveal uneven or hypo-echoic, hyperechoic or isoechoic echogenicity within the thyroid gland, which can identify single or multiple nodules, and can indirectly determine whether the nodule is benign or malignant by the description of the nodule. These are the tests for thyroid nodules, and it is recommended that patients who are suspected of having thyroid nodules should go to a regular hospital for the relevant tests.
