Key Statistics About Thymus Cancers

On this page

Although thymic tumors (thymomas and thymic carcinomas) are the most common tumors in the anterior mediastinum (the front part of the space between the lungs), overall they are rare. They occur at a rate of only 1.3 cases for every million people each year in the US. This works out to about 400 cases per year. (The exact number diagnosed each year is not known.)

Survival statistics for thymomas are discussed in Survival rates for thymus cancer.
