Pituitary tumors are almost always benign and not cancerous. The cause of pituitary tumors is not completely clear, and may be related to hypothalamic hormone regulation disorders, family inheritance, gene mutation, etc.. Pituitary tumor symptoms are mainly divided into two parts: symptoms related to pituitary tumor compression and abnormal hormone secretion. Clinically, almost all pituitary tumors belong to benign tumors, which are benign tumors occurring in the pituitary gland, mainly affecting the hormone secretion of patients, and will not have metastatic spread. Most of the pituitary tumors are resected by transsphenoidal surgery, and most of the patients can recover after the surgery. Some patients have tissue residue after the surgery, and can be treated with gamma knife in order to reduce the recurrence of the tumor; in addition, they can also be treated with medication, and the medication is mainly for the patients with functional pituitary tumors such as prolactinomas. Most of the pituitary tumors are benign tumors, which can be controlled by surgery and medication without affecting the life and work. Keep a good mindset and do regular checkups.
