How is the goiter in thyroid gland detected?

A goiter in the thyroid gland is typically detected through physical examination, where a healthcare provider palpates the neck to check for swelling or enlargement of the thyroid. Imaging tests, such as ultrasound, may also be used to assess the size and structure of the gland. Blood tests measuring thyroid hormone levels and thyroid-stimulating hormone (TSH) can help determine the underlying cause of the goiter. In some cases, a biopsy may be performed to rule out cancer.
