Prolactinoma is, by definition, a tumor of the pituitary gland that produces prolactin, leading to an excess of prolactin in the blood. The tumor is noncancerous and can occur in both men and women.
Some alternative names for this condition are: Prolactinoma - females; Adenoma - secreting; Prolactin-secreting adenoma of the pituitary.
Many women may recognize the hormone prolactin since it is responsible for triggering the production of breast milk, or lactation.
While the exact cause of this type of tumor is unknown, it is thought to be a piece in the puzzle of a hereditary disorder. Tumors of this nature are usually noncancerous, or benign, prolactinomas being the most common type of pituitary tumor.
While they are more common in women, men can get them as well. They are more often diagnosed in those under the age of 40.
In some cases, the tumors are very, very small and will never grow.
Larger tumors, called macroprolactinomas, are more common in men. Prolactinomas in men tend to occur at an older age and can grow to a large size before any symptoms appear.
