Pituitary tumors in the brain are benign tumors that grow slowly. When the tumor size is relatively small, there are generally no clear symptoms or signs, and most patients can work, live, and study like normal people. It is recommended to treat pituitary tumors with surgical methods. Most pituitary tumors are benign. If they can be completely removed through microscopic surgery, or through the transnasal transsphenoidal approach, minimally invasive surgery can achieve ideal treatment results and generally will not recur. However, for individual patients with pituitary tumors, if the tumor is malignant, it may easily adhere to surrounding tissues in the early stages, making it difficult to completely remove surgically, thus it is prone to recurrence.
