Thyroid Cancer Information
Thyroid cancer occurs when cancerous cells first form in the tissues of the thyroid, a butterfly-shaped gland located at the front of the neck. This disease often has no early signs or symptoms. As the cancer grows, however, symptoms may include:
- A lump or nodule in the front of the neck near the Adam's apple
- Hoarseness or difficulty speaking in a normal voice
- Swollen lymph nodes, especially in the neck.
The exact cause of thyroid cancer is unknown, but there are several risk factors that may increase a person's chances of developing it. For example, you may be at an increased risk if you:
- Are over the age of 40
- Are not getting enough iodine in your diet
- Have been exposed to high levels of radiation
- Are female.
