What is the outlook for people with pituitary adenomas?

The outlook depends on the size and type of adenoma you have. When treatment destroys the tumor, most patients who have benign adenomas can return to full, normal lives. Adenomas can recur, which means you will need treatment again. About 18% of patients with non-functioning adenomas and 25% of those with prolactinomas, the most common type of hormone-releasing adenomas, will need more treatment at some point. In some cases, adenoma treatment results in low hormone levels, and you have to take hormone medicines to replace what you have lost.
