Thyroid cancer is the twelfth most common cancer in the U.S. and makes up nearly 3% of all new cancer diagnoses. It is the sixth most common cancer for women in the U.S. Fortunately, most thyroid cancers respond well to treatment, although a small percentage can be very aggressive and deadly.
Key Facts
- An estimated, 44,280 new cases of thyroid cancer will be diagnosed in the U.S. in 2021, with 2,200 deaths expected to result from the diagnosis.
- The five-year survival rate for people with thyroid cancer is 98%.
- In the U.S., thyroid cancer incidence has more than tripled in the past three decades. Much of this rise appears to be the result of improved imaging techniques that can detect disease that might not otherwise have been found in the past.
- Women are about three times as likely as men to develop thyroid cancer.
- Although thyroid cancer occurs in all age groups, more than two-thirds of new cases occur in people between the ages of 20 and 55. This year, the disease will be the most commonly diagnosed cancer in people age 20 to 29.
