Thyroid nodules are small, benign (not cancerous) bumps on the thyroid gland (a butterfly-shaped organ in the front of the neck that regulates metabolism). Thyroid nodules can be solid or filled with fluid or partly solid and partly cystic. Some nodules can be easily seen or felt when touching the front of the neck. Others may be harder to see or feel, and evident only on a thyroid ultrasound or thyroid scan. In rare cases, thyroid nodules can be cancerous.
