What is a pituitary adenoma?
A person with a pituitary tumor has a benign growth of cells that have formed a mass in the pituitary gland, which is located in the brain. Benign tumors are not cancerous because they do not spread to other areas of the body. A pituitary tumor can cause the pituitary gland to reduce the production of some hormones, or increase the production of other hormones. The cause of pituitary adenoma is unknown, but genetics seems to play a role.

What are the symptoms of a pituitary adenoma?
Symptoms of a pituitary adenoma may include headache, vision changes, double vision, and eyelid weakness. Additional symptoms of pituitary adenoma depend on the type of tumor, and whether it produces too much, or too little, hormone.

How does the doctor treat a pituitary adenoma?
Treatment for a pituitary adenoma may include surgery, hormone therapy, or medications.
