Approved by the Cancer.Net Editorial Board, 04/2015

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 on the side of your screen.

Most tumors that begin in the thymus are thymoma. This cancer is uncommon, with less than 400 cases per year in the United States. Thymic carcinomas are much rarer and make up less than 1% of tumors that start in the thymus.

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 on how many people are diagnosed with this type of cancer are an estimate. The estimate comes from data based on people with this cancer in the United States each year. So, your own risk may be different. Doctors cannot say for sure how long anyone will live with thymoma.
