Treatment:

Pituitary tumors are usually not cancerous and therefore won't spread to other areas of the body. However, they can cause serious problems by putting pressure on important nerves and blood vessels.

Surgery to remove the tumor is often necessary, especially if the tumor is pressing on the optic nerves, which could cause blindness.

Most of the time, pituitary tumors can be removed through the nose and sinuses. However, some tumors cannot be removed this way and will require removal through the skull (transcranial).

Radiation therapy may be used to shrink the tumor, either in combination with surgery or for people who cannot undergo surgery.

The following medications may shrink certain types of tumors:

• Bromocriptine or cabergoline are the first-line therapy for tumors that release prolactin. These drugs decrease prolactin levels and shrink the tumor.
• Ocreotide or pegvisomant is sometimes used for tumors that release growth hormone, especially when surgery is unlikely to result in a cure.

Expectations (prognosis):

If the tumor can be surgically removed, the outlook is fair to good, depending upon whether the entire tumor is removed.

Complications:

The most serious complication is blindness, which can occur if the optic nerve is seriously damaged.

Permanent hormonal imbalances may be caused by the tumor or its removal. This may require replacement of the affected hormones.

Calling your health care provider:
