We don’t know a lot about what causes neuroendocrine tumors, so we don’t have many strategies to prevent them. We do know that people with certain risk factors are at a higher risk of developing neuroendocrine tumors.
Screening tests detect cancer’s hidden warning signs long before symptoms appear and when the disease is most treatable. Understand your screening needs and complete the cancer screening and prevention questionnaire to manage your cancer risk.Learn More
These risk factors include:
- A family history of multiple endocrine neoplasia type 1 (MEN1) syndrome.
- Von Hippel-Lindau syndrome
- Certain conditions that affect the stomach's ability to produce stomach acid, such as atrophic gastritis, pernicious anemia, or Zollinger-Ellison syndrome.
- Smoking tobacco
If you have one of these risk factors, your doctor may watch you closely. If you are at extremely high risk, your doctor may choose to remove an organ, such as the thyroid, to prevent a neuroendocrine tumor from growing there.
