A small number of pituitary tumors with small size and regular growth can be cured by Gamma Knife, but most of the pituitary tumors can only be controlled by Gamma Knife, and it is difficult to cure them completely. A small number of pituitary tumors with small size, regular growth, clear boundaries with surrounding tissues, and no infiltration and growth phenomenon can possibly be cured by Gamma Knife, and generally do not leave obvious sequelae. In most cases, the purpose of Gamma Knife treatment for pituitary tumors is to control the growth of the tumor and promote normal pituitary function, and it is generally applicable to patients who have recurrence or residual after surgery, who are unwilling to have open surgery or who cannot tolerate surgery. Gamma Knife can effectively control the continued growth of pituitary tumors, can promote tumor shrinkage and reduce the probability of recurrence, but usually can not achieve the goal of cure. It is recommended that patients presenting with pituitary tumors seek medical attention in a timely manner and be treated aggressively under the guidance of a doctor to avoid delays.
