Research & Facts

Some have estimated nearly 30%. In reviewing dozens of studies over the past 80 years on the Prevalence of Pituitary Tumors, the consensus was reached that at least 16.7% of the population develop or harbor pituitary tumors. Supported by the PNA and published by the American Cancer Society June 2004, the systematic review abstract "The Prevalence of Pituitary Adenomas" can be viewed at:

"1 in 5 individuals may have an abnormal growth on their pituitary gland, causing significant health complications that, if left undiagnosed and untreated, can impair normal hormone function and result in a reduced lifespan."

Take the first three steps

Step 1: Take action and get educated. Knowledge is Power!

The pituitary is a small, pea-sized gland located at the base of the brain that functions as "The Master Gland." From its lofty position above the rest of the body it sends signals to the thyroid gland, adrenal glands, ovaries and testes, directing them to produce thyroid hormone, cortisol, estrogen, testosterone, and many more. These hormones have dramatic effects on metabolism, blood pressure, sexuality, reproduction,and other vital body functions. In addition, thepituitary gland produces growth hormone for normal development of height and prolactin for milk production.
