Pituitary tumors

The pituitary gland is located in a bony indentation at the base of the brain just behind the eyes. The gland secretes hormones into the bloodstream that stimulate the thyroid to control many important bodily functions.

About seven percent of all brain tumors develop in the pituitary gland, amounting to about 1,300 diagnoses in the U.S. each year. Very few are fatal. But by overproducing hormones or blocking normal hormone production, pituitary tumors can create other problems, such as headaches, blurred vision, and—rarely—excessive urination and thirst. However, they often produce no symptoms.

Pituitary Tumor Program

The University of Colorado Tumor Program is nationally recognized to evaluate and treat pituitary tumors. One of the largest and most experienced programs in the country, it includes providers from multiple specialties to evaluate your tumor and symptoms.

Detection and staging tests for pituitary tumors

Once a cancer has been diagnosed, our specialists need to know where it may have spread. This is the “stage” of the cancer. The lower the number, the less it has spread. Knowing the stage allows your medical team to determine the best possible treatment plan for you.

Any combination of these tests and procedures may be used to find and classify (stage) pituitary tumors:

  • MRI (magnetic resonance imaging). Uses a magnetic field instead of X-rays to create detailed images of body structures and show the differences between normal and diseased tissues.
  • Blood test. Analyzes a sample of blood to evaluate hormone levels.

Treatments and therapies for pituitary tumors

Your multidisciplinary care team will work with you to develop a customized treatment plan based on the nature of your pituitary tumor and your personal preferences. Among the possible treatments:

  • Medication. Uses oral medication or injections to raise or lower hormone levels based on your pituitary tumor, the hormone imbalances it’s causing and your specific needs.
  • Surgery. Uses procedures performed by a specialized neurosurgeon when medication is not available or can’t be tolerated for treatment of a specific pituitary condition.
  • Stereotactic radiation therapy (stereotactic radiosurgery). Uses an external radiation procedure to precisely target and shrink pituitary tumors that can’t be completely removed by surgery; reduces radiation exposure to nearby brain tissue.
