Is the cancer of thyroid common?

Q. Is the cancer of thyroid common?
A. No, the cancer of thyroid is not common and that’s why it may take some time to detect it with the help of an ultrasound or Ct scan, it can be found out whether the lump that is developed in the throat is solid or cystic and scanning with the help of radioactive iodine may show ‘hot spots’ which are associated with cancer.
