A pituitary adenoma is an abnormal growth, or tumor, in the pituitary gland. The pituitary is a small complicated gland at the base of the brain. It makes several important hormones that regulate growth and the activity of several other major glands throughout the body. A pituitary adenoma is an abnormal growth, or tumor, in this gland. Pituitary adenomas are usually benign. This means they are not cancerous. They do not spread to other parts of the body. They can lead to vision problems because they are behind and near the eyes. A pituitary adenoma can also lead to growth problems. It often can also change the hormonal balance of the thyroid, adrenal, and gonad glands.
