Hormones are chemical substances secreted by cell communities or glands in the body. Pituitary gland tumor, which belongs to the hormonal system in the brain, is seen in 5-10% of all brain tumors. Pituitary gland tumor, in the type called macroadenoma, may cause vision loss – loss and deficiency in hormones secreted from the pituitary by compressing the surrounding structures when it exceeds its normal size (1 cm); In the type called microadenoma, it can cause excessive secretion of some hormones, for example, if excessive prolactin is secreted, milk coming from the breast even though the patient is not pregnant, and if excessive growth hormone is secreted, it can lead to pictures like enlargement of the hands and feet.
There are three approaches in the treatment of pituitary tumors: The use of drugs, surgical treatment in tumors that do not respond to medication (or macroadenoma causing sudden vision loss or bleeding into the tumor), surgical treatment (ie, through the nose called transsphenoidal, or by opening the skull bone from above). surgical removal of a pituitary tumor); and radiation therapy of choice for pituitary tumor that cannot be controlled by drug therapy and surgery or that extends to areas that are risky to reach with surgery.
