Although pituitary tumors can occur at any age, they're most likely to occur in older adults. People with a family history of certain hereditary conditions, such as multiple endocrine neoplasia, type I (MEN I), have an increased risk of pituitary tumors. In MEN I, multiple tumors occur in various glands of the endocrine system. Genetic testing is available for this disorder.
