Thyroid cancer is not common. It accounts for only
about 1% of all new cancers.1 For the year 2007, the
American Cancer Society expected approximately 33,550 cases of thyroid cancer
and 1,530 deaths from thyroid cancer in the United States.2
Most cases of thyroid cancer are diagnosed in people who are between
the ages of 25 and 65, although it can develop at any age. Thyroid cancer
occurs more frequently in women than it does in men.
