A growth: A pituitary tumor is simply a growth on the pituitary. It's not cancerous but it could cause problems by increasing or decreasing pituitary hormone secretion. It can also cause visual problems if it's big enough.

Tests.: If not already done, an MRI to confirm the tumor, and determine the size of the tumor. Lab tests to determine if the tumor is causing too much or too little of any pituitary tumor. If the tumor is larger than 1 CM (10 mm) or is making too much of anything other than prolactin, surgery may be advised. Medical treatment is often used to correct low hormone levels, or high levels of prolactin.

They are very small: These tumors secrete very powerful hormones that have far reaching affects on the body but many times the tumors are so small and also protected in the skull that they are not seen on standard imaging. Special imaging studies are needed many times to detect the tumors. Also, many of these hormones can be measured in the blood and if elevated, the search for the tumor is intensified.
