Risk factors

Factors that are associated with an increased risk of pancreatic neuroendocrine tumors include:

• Being male. Men are much more likely than women to develop these tumors.
• A family history of pancreatic neuroendocrine tumors. If a family member was diagnosed with pancreatic neuroendocrine tumor, your risk is increased. You may have multiple endocrine neoplasia, type 1 (MEN 1) syndrome, which increases the risk of this type of tumor.
