Number of New Cases and Deaths per 100,000: The number of new cases of thyroid cancer was 12.9 per 100,000 men and women per year. The number of deaths was 0.5 per 100,000 men and women per year. These rates are age-adjusted and based on 2007-2011 cases and deaths.

Lifetime Risk of Developing Cancer: Approximately 1.1 percent of men and women will be diagnosed with thyroid cancer at some point during their lifetime, based on 2009-2011 data.

Prevalence of this cancer: In 2011, there were an estimated 566,708 people living with thyroid cancer in the United States.

Survival StatisticsShow More

How Many People Survive 5 Years Or More after Being Diagnosed with Thyroid Cancer?

Relative survivalExternal Web Site Policy statistics compare the survival of patients diagnosed with cancer with the survival of people in the general population who are the same age, race, and sex and who have not been diagnosed with cancer. Because survival statistics are based on large groups of people, they cannot be used to predict exactly what will happen to an individual patient. No two patients are entirely alike, and treatment and responses to treatment can vary greatly.

Based on data from SEER 18 2004-2010. Gray figures represent those who have died from thyroid cancer. Green figures represent those who have survived 5 years or more.

Additional Information

Cancer stage at diagnosis, which refers to extent of a cancer in the body, determines treatment options and has a strong influence on the length of survival. In general, if the cancer is found only in the part of the body where it started it is localized (sometimes referred to as stage 1). If it has spread to a different part of the body, the stage is regional or distant. For thyroid cancer, 68.2% are diagnosed at the local stage. The 5-year survival for localized thyroid cancer is 99.9%.

Thyroid cancer represents 3.8% of all new cancer cases in the U.S.

3.8%

In 2014, it is estimated that there will be 62,980 new cases of thyroid cancer and an estimated 1,890 people will die of this disease.

Thyroid cancer is more common in women than men and among those with a family history of thyroid disease. The number of new cases of thyroid cancer was 12.9 per 100,000 men and women per year based on 2007-2011 cases.

Percent of New Cases by Age Group: Thyroid Cancer
1.8% under 20; 15.1% 20-34; 19.6% 35-44; 24.2% 45-54; 19.9% 55-64; 12.3% 65-74; 5.7% 75-84; 1.4% 85 and older

Thyroid cancer is most frequently diagnosed among people aged 45-54.

Changes Over Time

Keeping track of the number of new cases, deaths, and survival over time (trends) can help scientists understand whether progress is being made and where additional research is needed to address challenges, such as improving screening or finding better treatments.

Using statistical models for analysis, rates for new thyroid cancer cases have been rising on average 5.5% each year over the last 10 years. Death rates have been rising on average 0.8% each year over 2002-2011. 5-year survival trends are shown below the figure.

Cancer and the Thyroid

Anatomy of the thyroid and parathyroid glands; illustration shows the thyroid gland at the base of the throat near the trachea. An inset shows the front and back views. The front view shows that the thyroid is shaped like a butterfly, with the right lobe and left lobe connected by a thin piece of tissue called the isthmus. The back view shows the four pea-sized parathyroid glands.

This cancer forms in the thyroid gland, an organ at the base of the throat that makes hormones that help control heart rate, blood pressure, body temperature, and weight.

Four main types of thyroid cancer are papillary, follicular, medullary, and anaplastic thyroid cancer. The four types are based on how the cancer cells look under a microscope.
