Pituitary tumors are common in both men and women. The presence of a pituitary tumor may not cause any symptoms at all for some people. In fact, 25% of all people who develop small pituitary tumors can go undiagnosed for their entire life. Those in the medical field have not determined what the cause of these tumors is. However a person who develops a pituitary tumor is commonly thought to have inherited tendency for it.
