ON THIS PAGE: You will find out more about the factors that increase the chance of developing appendix cancer. Use the menu to see other pages.

A risk factor is anything that increases a person’s chance of developing cancer. Although risk factors often influence the development of cancer, most do not directly cause cancer. Some people with several risk factors never develop cancer, while others with no known risk factors do. Knowing your risk factors and talking about them with your doctor may help you make more informed lifestyle and health care choices.

The cause of appendix cancer is unknown, and no avoidable risk factors have been identified. The following factors may raise a person’s risk of developing appendix cancer:

  • Age. The only consistent risk factor for various types of appendix cancer is increasing age. Appendix cancer is rare in children.

  • Sex. Neuroendocrine tumors of the appendix are more common in women.
