Pituitary tumors are also called pituitary adenomas. They are small tumors that form in the pituitary gland. The pituitary gland is located at the base of the brain and releases hormones that influence the body’s growth, metabolism and maturation. Pituitary tumors interfere with normal hormone production.
Pituitary tumors account for about 10 percent of all primary brain tumors. Most are benign and can be cured.
Doctors classify pituitary tumors into two groups – secreting and nonsecreting. Secreting tumors release unusually high levels of pituitary hormones, which can trigger neurological conditions and symptoms including hyperthyroidism and Cushing’s syndrome.
