Pituitary disorders are caused by pituitary tumors and cysts or dysfunction of the pituitary gland itself. Pituitary tumors and cysts occur sporadically and although occasional genetic abnormalities have been identified in some pituitary tumors, there are few consistent findings.
Pituitary Tumors. The most frequent type of pituitary disorder is a pituitary glandtumor. These tumors are fairly common in adults. They are not brain tumors and are almost always benign (that is, not cancer).In fact, cancerous tumors of this sort are extremely rare. There are two types of tumorsâsecretory and non-secretory. Hyposecretion can also result from surgery or radiation of a tumor. 2  Tumor mass effects: As a pituitary tumor grows and presses against the pituitary gland or other areas in the brain, it may cause headaches, vision problems, or other health effects.
