The pituitary gland is found in the skull, just above the nasal passages. It's connected to the brain in the hypothalamus area, and the gland is considered the body's most important hormone regulator. The pituitary gland monitors the activity of all of the other glands in the body. Malignant pituitary tumors--tumors exhibiting cancerous cells--are rare, but benign varieties can be uncovered. The diagnosis process for this form of cancer is similar to other types, but because brain scans are not routinely administered, it's rare to diagnose this disorder in the early stages.
