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

Currently, the only factor researchers have found that may raise a person’s risk of developing an islet cell tumor is a hereditary condition called multiple endocrine neoplasia, type 1 (MEN1). MEN1 increases the risk of developing tumors in three glands: pituitary, parathyroid, and pancreas.
