Second Opinion with Joan Lunden S08E07 - Pituitary Gland Tumor

The pituitary gland is a pea-sized endocrine gland located at the base of the brain. The pituitary helps control the release of hormones from other endocrine glands, such as the thyroid and adrenal glands. The pituitary also releases hormones that directly affect body tissues, such as bones and the breast's milk glands. A pituitary gland tumor is an abnormal growth in the pituitary gland, the part of the brain that regulates the body's balance of hormones.
