Tumors Causing Hormone Overproduction Or DeficienciesAlthough it is not known what causes a tumor in the pituitary gland to form, the causes of the symptoms a tumor can have are known, although not all tumors cause symptoms.
A functioning tumor in the pituitary gland can cause hormone overproductions or hormone deficiencies which can include abnormal levels of growth hormones.
Most of the symptoms tumors in the pituitary gland produce are related to these hormonal imbalances in the body or brain.
