Appendix cancer

Appendix cancer risk factors

Risk factors for appendix cancer may vary. Risk factors for appendix cancer often involve lifestyle habits, age, medical history and other considerations. Having risk factors does not mean someone will get cancer. Some people who have multiple risk factors never develop appendix cancer, while others get the disease despite no known risk factors.

Risk factors include:

Smoking: Smokers are more likely to develop appendix cancer than non-smokers.

Family history: Patients with a relative who has or has had appendix cancer or multiple endocrine neoplasia type 1 (MEN1) syndrome (also known as endocrine adenomatosis or Wermer syndrome) have a higher risk.

Medical history: Those with a history of certain medical conditions that affect the stomach’s ability to produce acid, such as atrophic gastritis, pernicious anemia and Zollinger-Ellison syndrome, are at an increased risk for appendix cancer.

Gender: Women are more likely to develop carcinoid tumors than men.

Age: The average age at diagnosis is 40.
