Pituitary Tumor

Causes of Pituitary Tumor

The cause or causes of pituitary tumors are unknown. There are, however, some studies that link multiple endocrine neoplasia type 1 (MEN 1), a hereditary condition, to a high risk of pituitary tumors, parathyroid tumors and pancreatic tumors. That said, MEN 1 is associated with only a small percentage of pituitary tumors. Other risk factors include multiple endocrine neoplasia type 4 (MEN 4), an inherited syndrome that can lead to an increased risk of both pituitary tumors and a type of benign kidney tumor, and rare inherited and non-inherited genetic problems, such as changes in the gene called AIP.
