Pituitary Tumors

pituitary tumor is an abnormal growth of cells in the pituitary gland, which is the main hormone-producing gland in the body. About the size of a pea, the pituitary gland is located in the center of the brain behind the nose and eyes. Hormones are chemical substances the body produces that control and regulate certain cells or organsA tumor in the pituitary gland can disrupt the normal balance of hormones in the body and affect a person's health.

Our multidisciplinary team of doctors, neurosurgeons and specialists from several departments within Johns Hopkins Medicine, including the Comprehensive Brain Tumor Center, offers patients individualized treatment plans.

What You Need to Know

  • About 10% of all primary brain tumors are pituitary tumors.
  • Only a very small number of pituitary tumors are malignant (cancerous). Many pituitary tumors do not cause health problems almost all pituitary tumors can be treated, usually through medications and surgery.
  • Because of the location of the pituitary gland, at the base of the skull, a pituitary tumor grows upward. Eventually, some pituitary tumors will press against the optic nerves, causing vision problems.
  • There is no obvious cause of pituitary tumors, but one percent to five percent occur within families. Some pituitary tumors might be caused by stimulation from the hypothalamus — a part of the brain that signals the pituitary gland to make hormones.
