How you came to know that thyroid gland is cancerous or not?

Fine-needle aspiration (FNA) biopsy

This is the most common way to diagnose thyroid cancer. A thin needle is inserted into the thyroid gland to remove a small sample of cells. The cells are then examined under a microscope to look for signs of cancer.

Thyroid ultrasound

This is a painless procedure that uses sound waves to create images of the thyroid gland. It can help to identify thyroid nodules, which are abnormal growths of tissue in the thyroid gland. Some thyroid nodules are cancerous, while others are not.

Thyroid blood tests

These tests measure the levels of thyroid hormones and other substances in the blood. Abnormal levels of these substances can indicate thyroid cancer.

Thyroid scan

This is a procedure that uses radioactive iodine to create images of the thyroid gland. It can help to identify thyroid nodules that are not visible on ultrasound. Some thyroid nodules that are not visible on ultrasound are cancerous.

Biopsy of the thyroid gland

This is a surgical procedure in which a small piece of the thyroid gland is removed and examined under a microscope. This is the only way to definitively diagnose thyroid cancer.

Symptoms of thyroid cancer

In addition to the tests and procedures described above, the following symptoms can also indicate thyroid cancer:

* A lump in the neck

* Difficulty swallowing

* Hoarseness

* Persistent cough

* Unexplained weight loss

If you are experiencing any of these symptoms, it is important to see your doctor right away.
