symptom thyroid : Facts About Thyroid Cancer & Nodules

The thyroid is a small, butterfly-shaped gland located at the base of the neck, below the Adam’s apple. Although it only weighs about an ounce, the thyroid can have a tremendous impact on your health. The thyroid’s function is to create thyroid hormone, which regulates every aspect of your metabolism.

Thyroid Cancer
Cancerous thyroid nodules are often detected by a lump in the thyroid or swelling in the neck. The majority of people with thyroid cancer have excellent long term prognoses due to the availability of safe and effective therapies.

Here are some additional facts about thyroid cancer:

Thyroid cancer is the most common cancer of the endocrine system (glands).
The American Cancer Society estimates that in the year 2005 about 25,690 new cases of thyroid cancer will be diagnosed in the United States.
The rate of thyroid cancer is increasing (determined by a 3% per year increase in the actual rate per 100,000 people).
Women are more likely to suffer from thyroid disease than men.
Thyroid Nodules
Normal thyroid cells may grow, forming a solid or fluid-filled lump in the thyroid. There are generally no symptoms. However, nodules may grow large enough to press on the trachea or esophagus, or may cause hyperthyroidism. Only 5% of nodules are cancerous.
