Pituitary Gland Tumor: Statistics

Approved by the Cancer.Net Editorial Board, 11/2014

ON THIS PAGE: You will find information about how many people are diagnosed with a pituitary gland tumor each year and some general survival information. Remember, survival rates depend on several factors. To see other pages, use the menu on the side of your screen.

About 10,000 pituitary gland tumors are diagnosed in the United States each year. Most of these tumors are noncancerous. Because the pituitary gland is located next to the brain, this type of tumor is sometimes classified as a brain tumor in data collection, including by the World Health Organization. Pituitary gland tumors are more common in older adults.

People with a tumor located in the cerebellum, spinal cord and cauda equina (bundle of spinal nerves), cranial nerves, pituitary and pineal glands, and nasal cavity have higher survival rates. The ten-year survival rate is the percentage of people who survive at least ten years after the cancer is found. The ten-year survival rate of people with a pituitary gland tumor ranges from 60% to more than 90%.  

Cancer survival statistics should be interpreted with caution. These estimates are based on data from thousands of people with this type of tumor in the United States, so the actual risk for a particular individual may be different. It is not possible to tell a person how long he or she will live with a pituitary gland tumor. Because these survival statistics are measured in ten-year intervals, they may not represent advances made in the treatment or diagnosis of this cancer. Learn more about understanding statistics.
