Treatment for a pituitary adenoma, or a benign tumor that develops in the pituitary gland, will vary based on the tumor’s size and whether it is functioning or nonfunctioning. The pituitary gland is a small structure located at the skull base that regulates hormones and controls other glands throughout the body.

Nonfunctioning adenomas are often asymptomatic, but may require treatment if they grow large enough to impair normal gland function or press against a nearby nerve or the brain. This can lead to headaches and vision changes. When treatment is necessary, surgery is usually recommended to remove large adenomas (macroadenoma). Radiation therapy may also be used to destroy tumor cells that remain after surgery.

Functioning adenomas, on the other hand, produce excessive amounts of hormones that can create imbalances and disrupt various bodily functions. Signs of a hormone-producing adenoma may range from rapid weight gain and decreased sex drive to increased sweating and high blood pressure, among dozens of other potential symptoms. Treatment for a functioning tumor can vary based on the type of hormone being produced in excess and the resulting symptoms. For most patients, surgery will provide the best chance of hormonal control, but medication or radiation may be used to control symptoms.
