Pituitary Gland Tumor: Statistics

Approved by the Cancer.Net Editorial Board, 01/2020

ON THIS PAGE: You will find information about the number of people who are diagnosed with a pituitary gland tumor each year. You will also read general information on surviving the disease. Remember, survival rates depend on several factors. Use the menu to see other pages.

About 14,120 pituitary gland tumors will be diagnosed in the United States this year. Very few of these tumors will be cancerous. Older adults are more likely to be diagnosed with this type of tumor, but it can occur at any age.

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.

The 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Percent means how many out of 100. The 5-year survival rate for people with a pituitary gland tumor is 82%. Survival rates depend on the type of tumor, the person’s age, and other factors.

In general, it is important to remember that statistics on survival rates for people with a pituitary gland tumor are an estimate. Experts generally measure the survival statistics every 5 years. So estimates may not show the results of better diagnoses or treatment available for less than 5 years. Talk with your doctor if you have any questions about this information.
