Pituitary Tumor

Pituitary Tumor Symptoms and Causes

Most pituitary tumors are not cancerous. About 1,300 pituitary tumors are diagnosed each year. However, because many of these tumors do not cause symptoms or affect health, many are not diagnosed or are found incidentally during routine brain imaging studies. When there are symptoms of a pituitary tumor, they can range from headaches, vision loss, nausea and vomiting to fatigue, weakness, hair loss and low blood pressure. Pituitary tumors are a result of uncontrolled cell growth in the pituitary gland, but the causes remain unknown.
