Thyroid Cancer

Cancer of the thyroid occurs more often in people who have undergone radiation to the head, neck, or chest. However, it may occur in people without any known risk factors. Most thyroid cancer can be cured with appropriate treatment. Thyroid cancer usually appears as nodules within the thyroid gland. Some signs that a nodule may be cancerous include:
  • Presence of a single nodule rather than multiple nodules
  • Thyroid scan reveals the nodule is not functioning
  • Nodule is solid instead of filled with fluid (cyst)
  • Nodule is hard
  • Nodule grows fast
