ON THIS PAGE: You will find information about how many people are diagnosed with this type of cancer each year. You will also learn some general information on surviving the disease. Remember, survival rates depend on several factors. To see other pages, use the menu.
Most tumors that begin in the thymus are thymoma. This is an uncommon cancer. Less than 1 person per 1.5 million people develop thymoma. This means about 400 people per year develop thymoma. However, the exact number is not known and may be increasing with the use of computed tomography (CT) scans (see Diagnosis).
Thymoma usually occurs in people between the ages of 40 and 60, but can occur at almost any age. Survival rates are different depending on several factors, including the stage and classification of thymoma (see Stages).
It is important to remember that statistics for how many people are diagnosed with thymoma are an estimate. The estimate comes from annual data based on the number of people with this cancer in the United States. People should talk with their doctor if they have questions about this information. Learn more about understanding statistics.
