Signs of Pituitary tumor

Pituitary Tumor

Description

Abnormal growths in the pituitary gland usually come from one of the cells of the anterior pituitary. The pituitary gland controls the production of many hormones and a tumor in this area can cause alterations in these hormones. The optic nerve passes next to this gland in the brain, and tumors of the pituitary can affect vision by compressing on this nerve.

Symptoms only in women: abnormal nipple discharge, stopping of menstruation, excessive body hair. Symptoms only in men: breast development and impotence.

Tests

A history and physical exam will be performed. Tests to measure the hormonal effects of the tumor are done. A MRI scan is done to identify the tumor.

Treatment

Surgery to remove the tumor is often necessary. Most of the time, pituitary tumors can be removed through the nose and sinuses. Radiation therapy may be used to shrink the tumor, either in combination with surgery or for people who cannot undergo surgery. The following medications can reduce the size of certain types of tumors: bromocriptine, cabergoline, ocreotide, or pegvisomant. American Cancer Society: (800)227-2345
