tumors/DS00533 Pituitary tumors are abnormal growths that
develop in your pituitary gland. Some pituitary tumors cause
excessive production of hormones that regulate important
functions of your body. Other pituitary tumors can restrict
normal functions of your pituitary gland, causing it to produce
lower levels of hormones. The vast majority of pituitary tumors
are noncancerous growths (adenomas). Adenomas remain confined to
your pituitary gland or surrounding tissues and don't spread to
other parts of your body. Treatment for pituitary tumors
involves various options, including removing the tumor,
controlling its growth and managing your hormone levels with
medications. Your doctor may recommend observation — or a ''wait
and see'' approach. A pituitary tumor can cause your pituitary
gland to produce too much or too few hormones,
