You have benign abnormal tissue in the pituitary gland.

When there is abnormal growth of tissue in an organ, then this is also referred to as a tumor. The tissue in the body is made up of cells. A tumor disorder involves the cells multiplying more than normal. This results in abnormal or excess tissue forming. A tumor can be benign or malignant. The tumor you have is benign. Benign tumors do not destroy the healthy tissue and do not spread throughout the body.

The pituitary gland is a gland in the brain. Many messenger substances are created for the body in this gland. These messenger substances influence growth, metabolism and sex hormones, for example.

A tumor of the pituitary gland can therefore lead to a great range of symptoms. A tumor in the pituitary gland can press on the brain and nerves. This can cause you to have visual disturbances, a headache or vomiting. The pituitary gland also produces lots of hormones. A tumor in the pituitary gland can cause the quantity of messenger substances to be different than normal. Body growth can be changed, for example. You can then have very large hands. The body may also not able to respond well to stress because the formation of stress hormones is altered. Sex hormones can also be changed. Hair growth and your voice can be changed.
