What is a Pituitary Tumor?

Pituitary tumors are abnormal growths that develop in or adjacent to your pituitary gland. Sometimes pituitary tumors can cause excessive production of hormones that regulate important functions of your body. Other times, pituitary tumors can restrict your pituitary gland, causing it to produce lower levels of hormones. Most pituitary tumors are noncancerous, non-spreading growths (adenomas). Adenomas remain confined to your pituitary gland or surrounding tissues and don't spread to other parts of your body. To learn more about treatment for pituitary tumors, or to schedule an appointment, please call (407) 303-1700 or click here to fill out an online assistance form.

Some symptoms that are seen from those with pituitary tumors are headaches, vision loss, watery nasal drainage, nausea and vomiting, hormonal changes, fatigue, weakness, cold intolerance, constipation, low blood pressure, body hair loss, sexual dysfunction, breast engorgement or discharge, and unintended weight loss or gain. Treatment for a pituitary tumor depends on your type of tumor, size, and location.

Causes of a Pituitary Tumor

Currently, the cause of pituitary tumors is unknown, but scientists are working to find more evidence as to why these tumors are created.

Tests to Diagnose a Pituitary Tumor

Your physician may conduct the following tests in order to diagnose a pituitary tumor:

  • Blood and urine tests. A blood and urine sample can help your physician determine if you have an overproduction of deficient production of hormones.
  • Brain imaging. A computerized tomography (CT) or magnetic resonance imaging (MRI) scan of the brain can help your physician determine the exact size and location of a pituitary tumor.
  • Vision testing. Testing your vision can help your physician determine whether the tumor has impaired your ability to see.
