What are pituitary tumors?
A pituitary tumor is an abnormal, uncontrolled cell growth in your pituitary gland. These tumors can cause the pituitary gland to produce either too much hormone, or too little. This change in hormone levels can cause a wide range of symptoms.
The pituitary gland is a small gland at the base of your brain, behind your nose. It influences almost every function of your body by controlling the release of most of the body’s hormones, which it also produces. These hormones regulate growth, blood pressure, reproduction, and many other bodily functions.
Are pituitary tumors cancer?
No, most of them are benign (not cancerous), and do not spread to other parts of your body. They tend to grow very slowly.
How common are pituitary tumors?
They are the fourth most common type of brain tumor, and the most common disease affecting the pituitary gland. They are most common in people in their 30s or 40s, but can occur in children.
