Thyroid cancer is the cancer that originates from the tissues of the thyroid gland. Symptoms may include a lump or swelling in the neck. Risk factors may include family history, radiation exposure at a young age and having an enlarged thyroid. There are four main types –follicular thyroid cancer, papillary thyroid cancer, anaplastic thyroid cancer and medullary thyroid cancer. Worldwidely, as of 2015 about 3.2 million people suffer from thyroid cancer. In 2012, about 298,000 new cases occurred. It most likely occurs from the ages of 35 to 65. Women are affected more often than men. Those of Asian descent are more likely affected. Diagnosis is often based on fine needle aspiration and ultrasound. Focal adhesion kinase acting as a marker of invasive potential in differentiated human thyroid cancer has been studied.
